While we are waiting for reply from MSIL, has anyone tried some temporary fix for this issue? I am not talking about full suspension upgrades, but would something like Rogerab Coil Spring Buffer Kit prevent the damage to propeller shaft?

I have installed these on my Jimny. They are taller bump stops. They do make a difference by reducing the articulation to an extent and thus reduce that characteristic ‘thud’ which is common in the Jimny when going over these sharp speed breakers.
In theory, these can also help reduce the propensity of the prop shaft rub problem.
If one wants to buy these they can be got from AM Racing in Delhi for about 7000 the pair. (I am just a customer of theirs and have no personal interest in them otherwise.)
Yes they are expensive. I dont deny that. But so far I am finding them useful.
It is also worth stating that my Jimny is ‘stock’ and there is no ‘lift’ and Im running on the OEM tyres as well.
However I have neither encountered nor tried and tested the prop shaft ‘rub’ bangle thing. I don’t go hard core off road but confine myself to trail drives if at all.

The Galaxy Grey Thunder Edition ‘Trail Rated’ Jimny in the pic is mine. I bought it second-hand in March from Spinny Bangalore. It had done 736kms when I got it. I have now clocked about 2600kms. It is a joy to drive in the city and even on the highway - Ive driven to Mysore and back and had a lot of fun doing that. Im very happy with its Naturally aspirated 1.5 litre engine. I love taking it up to the top revs in eaxh gear. It is like a 4 wheeled motorbike. It is perfect for me, as a lifelong Gypsy enthusiast and owner, because it is the modern Gypsy. It brings out and enhances my happy side in an indescribable manner.

The Green/ Kinetic Yellow Jimny in the picture is some other person’s.

Thanks. BTW, surprised to know that you bought a Jimny since you already have Thar 3 door. Is the Thar still with you?

No surprises there at all Sir. I will answer in a long winded way.

I sold my Rocky Beige Feb 2021 Thar in Feb 2024 after exactly 3years 14 days with 30,000kms on the clock. It was sold to Spinny at the very good price (according to me) of Rs 14 lac. Of course I had returned it to near stock condition after removing all the accessories I had fitted. I gave away all the expensive AVO suspension components and underbody protection accessories and things to my good friend.

Incidentally, I also sold my stock civilian soft top Gypsy around the same time, to my friend. And this was sold for the same price I bought it for. Because such a stock genuine civilian un-abused vehicle is an absolute rarity.

The reasons for my selling the Thar are as follows and I have no hesitation in admitting to myself or publicly that I simply stopped ‘loving or even liking’ it and that led to the ‘parting of ways’ , if I may;
a. I became very weary of its perpetual jiggliness and bumpiness even after the AVO suspension upgrade.
b. It used to cost me 10K for each trip to Coorg or Ooty by way of Petrol because of its rank fuel inefficiency. For a monthly driving average of 800kms during the 3 years I had it, I used to pay a petrol bill of Rs 10K. This is terrible by any standards. Irrespective of the depth of one’s pockets, this is a big pinch and I belong to the section with relatively ‘shallow pockets’ and a marked unwillingness to ignite hydrocarbons quite in that manner, while also paying the usurious ‘Madam’s’ Taxes to boot.
c. I no longer enjoyed the Thar’s ‘bulk’, ‘hugeness’ and ‘wideness’ especially on the narrow hill roads and the daily city drive.
d. Not being a fervent worshipper at the altar of ‘road presence’, I was increasingly finding that the impression and reputation of the ‘new age’ ‘Thar Owner/ Driver’ was growing ‘out-of-sync’ with who I am, as a person. And I say this despite, as many here know, having been an owner of multiple Mahindra (Diesel) vehicles and Maruti Gypsys in the last so many years.
f. I found, as I have said many times, that the Jimny, being compact, light, narrow and comfortable - a modern Gypsy in fact, was far more suitable for my particular needs, wants, preferences and personality type, than the Thar can ever be.
g. I also bought a Hyundai Kona EV in March. And as Ive written on another thread basis my observations in the last 6 months of ownership, the Kona costs me 15% of what the Thar used to cost, to run (by way of Electricity Charging cost vis a vis Petrol.)

Even if Maruti comes up with a solution, will they also replace the damaged propellor shafts? It has been 2 months since the issue was last reported, why have'nt they come up with a solution?

I don't have any expectations from Maruti to be frank. They don't even acknowledge an issue because it's a Maruti Suzuki, how can it have any problem.
Getting a thing replaced under warranty needs too much of haggling. I don't have time and patience to go through that. Also, all those test drives they do to look for the problem at the expense of my fuel. Brilliant product i.e Jimny is absolutely ruined by the 'Chalta hai' attitude of Maruti Suzuki

[Shanksta]

Is there any update on this issue ?

I don’t see any more reports here apart from the members that have reported the prop shaft “bangle” earlier. Can it assumed the that this is more of a batch issue.

I am planning to get the Jimny and will definitely be carrying at least 3-4 people(healthy adults) for 40% of my intended use. This issue still worries me, hence the query.

If possible could you measure the Height of the bump stops and post it. It would be extremely helpful!
Thanks in advance!

Here is the link to the products.

You can order direct from Japan but you will have to pay the shipping and duty levies. Alternatively you can ask the chaps at AM Racing Delhi for them. They will offer you a ‘landed’ price including the shilling and duty etc.

https://compassauto.jp/collections/s...tops-for-jimny

The screenshots attached here offer more details including the measurements of these.

Beyond this I have carried out another small set of enhancements ;
a. shock absorber extenders for the Jimny, bought on Compass Auto.
b. Longer rear brake fluid hose again from Compass Auto which helps compensate for the marginally increased height.
c. stiffer body mounts procured from AM Racing.

https://compassauto.jp/collections/s...42516962410654

The combination of the taller bump stops fixed a couple of months ago plus the stiffer body mounts and the shock absorber extenders have made a complete difference in the feel.

(While changing to the extended brake hose I also bled and changed the fluid to Bosch ENV6 which is better than stock OEM.)

With all these enhancements, the ‘thud’ which was already mitigated significantly with the addition of the taller bump stops a few months ago has completely gone.

I can safely say this having driven more than 150kms after fixing these.

For greater clarity here are my observations.

I note that putting these extenders and the combo described above seems to have roughly the same effect as using those suspension modulators by Rogerab and Jupitune and similar. But this is a much more ‘engineered’ fix.

Basically this extender being bolted on to the shock absorber mount, increases the shock absorber mounting height by 3.5 centimetres (~1.25 inches) which is near-negligible. But I have not fixed taller springs, so, the nett effect is probably very much less (~1.5 cm or 0.75 inch) in terms of raising the ‘height’. Yet, it seems to do exactly what it is meant to do, which is to remove the Thud.

Whereas the suspension modulator is fixed within threaded onto the springs and secured with those plastic tags, these enhancements are bolted on thoroughly.

All of these, cumulatively acting in tandem, perform the job of retarding articulation and in the Jimny it stops the Thudding. In other cars the suspension modulators stop the car bottoming out on our unscientific speed breakers.

Now, my vehicle never carries any passengers at the back and most probably never will either.

There are only the tool bags etc sitting there to provide a little ballast.

So again, so far, in my observation, with the taller bump-stops, these shock absorber extenders and the stiffer ‘single piece’ harder rubber body mounts, I am seeing that my vehicle is handling better and of course, with our unpredictable Giant speed breakers, one is not as prone to those ‘butt clenching’ moments since the thudding is gone now, plus as a bonus one can carry greater speeds around corners with lesser trepidation.

Because whatever body roll was there because of the softer body mounts, has definitely reduced with these stiffer ones.

Basis my observations so far, these performance enhancements that I have done, are decidedly NOT a Placebo, even if my vehicle is mostly stock OEM and not one of those lifted ones.

All of these are completely reversible. And can be mounted on stock vehicles without ‘lifting’.

In fact I don't ever intend to lift the Jimny because I have no need to.

Ive not even changed the tyres and don’t intend to until the factory fitted ones become worn.

I hope this helps others as it has helped me.

(Other than being a Customer, I have NO Connection to either AM Racing Delhi or Compass Auto Japan.)

(The next modification Im going to do is a brake upgrade - a complete Brembo set. Rotors, front pads and rear shoes.)

I have observed my Dot 3 brake fluid getting darker in under 2000 kms of driving, with a bit of gunk attached to the filter element of the brake fluid reservoir. All this was back during the heat wave in the month of September. How is your feedback with Bosch ENV6 brake fluid? Is it worth the price?
Viscosity of ENV6 is lower than Dot 5.1 and also has high dry boiling point.
I am planning for Mannol Dot 5.1 brake fluid and a simple DIY for brake fluid flush.

I have done DIY installation of Rogerab spring buffers on all four springs. Reason being, when I carry stuff in the boot of my Jimny, the rear sags and gets me worried about propeller shaft bangle. Yes, not a very hi-tech solution but lets see how it pans out.

Here is the one I am using.
This is better than the OEM.
I will post more about it after I do my brakes upgrade and then test.

Propeller shaft issue is not limited to 4 door Jimny. I did see a YouTube video from South Africa or Australia that mentions about this on the 2 door version. I will try to find that and pist for reference but there is no info but more of the custom changes he did to avoid this.

[Aero007]

I purchased my Jimny about 6 months ago and I was aware that Jimny 5 door owners are reporting sporadic cases of rear prop-shaft touching the crossmember owing to extreme rear axle articulation or high vehicle load (maybe even a combination of both). I have, for the most part, had an amazing ownership experience and I recently clocked 14k kms on my Jimny.

My typical use case for my Jimny is 90%-On-Road and 10%-Very Light Off-Road. I say "Very Light Off-Road" because I use my Jimny to go to my farm which has a dusty and relatively well beaten off-road patch of about 2kms which, I am sure, does not even require a 4x4 to pass.

Coming to the prop-shaft issue, since I was aware that this issue existed on some cars, I made it a point to check my car regularly to look for signs of this issue. I did not find anything for about 5.5 months of my ownership. I recently went on a trip to Madurai from Bangalore which was 99% highways. I was washing my car after the trip and when I checked, surprisingly enough I found the infamous "bangle" on my Jimny's prop-shaft. I dont remember nor recall when this might have occurred.

I can clearly see the scrape on the prop-shaft and the undulation of it can be clearly felt with bare hands. There is also a scrape on the crossmember at the location of the contact. Looking at the bangle on the pro-shaft, it looks like it not only scraped away the coatings on the top but also it dug into some metal. Since this will act as a stress concentrator(a notch on a cylinder with predominantly twist/torque loading), there is a likelihood that it will fail prematurely.

This surely looks like a very concerning and serious problem. I have not yet taken it to a service center and I will definitely pay a visit soon. Does anyone have any latest updates from MSIL regarding this particular issue?

I am new to the forum hence please excuse me if I have posted anything wrong.
Does anybody know if MSIL has silently solved propeller shaft issue in MY 25 models because Jimny has got two bulk orders.
One from Japan for fulfilling 50,000 orders and one from Indo Tibetan Border Police for 60 Jimny vehicles.

[Sankar]

This is an OE solution for extended bump stop for the rear end of the Jimny. The part number is 42110M77A10 and can be sourced through MGP store or boodmo. It is Maruti Eeco's rear bump stop. Just screw off stock and screw in Eeco's easy as that.







By design much better than block type bump stop rubbers.
