I am new to Gypsy but building my knowledge because a buy is planned this year. Can anyone please explain what is this all about -

1. Should the 4X4 never be used on tarmac ? (I know why will anyone use it but if unintentional engagement happens like in this case)
2. During Offroad is there a time limit for max. time one can use the 4X4 ?

nothing to worry if you have not taken any U-Turn kind of thing at high speed.
I had driven many times on 4x4 low for 50-60 kms, normally in rallies we don't disingage the 4X4 low irrespective of the surface.

I had never faced any problem because of using 4x4 low on tarmac. I hope it gives you some relief.

+1, check for any oil leaks underneath (which may have developed or aggravated after this incident).

As others have said, ntomer, no need to worry at all....I have driven about 35 kms in 4L (when it got stuck in 4L), with some pretty sharp turns on the way...my Gypsy runs smoothly today, without any issues.

Does your gypsy make this sound above 60 km in fifth gear. Does it increase at 80 km/h.

Try 60 km/h in 2nd or third gear. It won't be there.

If above symptoms are there, this sound is coming from 4X4 transfer case. Two bearing and a small shaft needs to be changes as the shaft has become uneven and the bearing are making this sound. The three parts would cost about Rs. 3000/-.

These are all SGP parts.

[Torque-ative]

Most Gypsy's at Dessert Storm or Raid de' push their vehicles flat out in 4x4 HI.

I wonder if the light nature of the Gypsy lets the transmission un-wind, by letting the tires slip a little even on tarmac,..or trial driving.

[wanderhermit]

In a rally, transmission winding is not a huge concern as there is lot of excessive wheel spin and jumps. And gypsy transmission is one of the most sturdy available. It does winds up easily.

Also their is not much tarmac for a long stretches. Raid and DS organisers make sure of that

And the parts that I have mentioned above, plus leaf springs, diff tubes, shockers (all eight), bush kit, clutch and oil changes are done in most of the cases. These parts take the maximum brunt.

In fact, top drivers manage to destroy suspension (leaf springs and shocks) during a rally only. And these are tiger red. Which are really good.

Dear Wanderhermit,

Could you please look at: http://www.team-bhp.com/forum/4x4-ve...ml#post2612688

I think I am facing similar problem. Would you suggest the same for my MM540?

With thanks,
