Doubts

qqplus · 27th December 2004, 08:51

Hello,
I have some doubts which I hope to clear here. I was reading a thread yesterday when I read some user's post that he does 100 kmph in his 800 and the car doesnt wobble. Well, my car DOES start to wobble after 80. What could be the reason folks? Plz. Im also very particular about my car so I want to clear this thing asap.

Secondly, I know many of you must have seen WWE on television. And those who have watched it, must be knowing Eddie Guerrero and his lowriders. Since I watched him for the 1st time, im wondering how his car could jump up and down, tilt and do other things while not in motion. As far as I know, it is some mechanism which is fitted in ur boot and its called 'Hydrolics' or something like that. But would like to get the right n exact info here.

Thanks.
Awaiting reply.
AJO.

Lowriders have also fascinated me. Basically, lowriders as the name suggests the main purpose was to ride low but speed breakers and bad roads brought about a bit of change and thus gave born to this jumping up and down loll.
Cars are fitted with Hydraulic Kits which has the ability to raise and do the opposite to the car. Its kinda costly process. Bottomline this hoping of car is a due to two things one hydraulics and second connecting it to shock absorbers or springs voila theres your lowrider.

okay,
i know it is costly. but can it be fitted in India?

qqplus · 27th December 2004, 11:09

but anyways thanks very much for the info man.

hey you can get these suspension kits from abroadand get them fitted over here..
they are cheapest in the states..start at around 40k...depending on the features and size...fitting can be done by a mech in india

qqplus,

About the high speed wobble in your car, it could be a LOT of factors causing this... i will list a few -
1. Wheel alignment (&balancing if the tires begin to "hop" at a certain speed)
2. Old and word steering bushings etc
3. Worn CV joints
4. Suspension problem
etc

If you get someone who is knowledgeable enough, to drive your car, he may be able to pinpoint the reason.

Ok,
I think its better to visit the service station once and then find out the exact reason. Last night I also discovered another thing, that is the driver side front door sounds different than other 3. There is more sound of metal than b4.

Hmmm... should check out. Well.....thanks anyways.

AJO.

i think u must go for wheel balance...probably that would solve your problem

tsk1979 · 10th February 2006, 11:47

800 if set up properly does not wobble even at 120kmph on speedo, though crosswinds can make it fly.
Wobbling is of two kinds
1. Steering wheel vibration : This is 90% due to imbalanced wheels. Now after wheel balancing also you may get this wobble in old cars. Reason bent rims. Not the obvious bends near edges, the rim gets bend structurally, so wheel balancing does not work too.
The only solution here is to replace rim.
2. Suspension related vibration : 800 has(atleast 1998 models had) lousy rubber bushkits costing 100rs or so for the entire set. If your car is driven extensively on bad roads these bush kits get worse and worse, and it appears that your car starts bouncing up and down from front at high speed.

Apart from this there is slow speed wobble. If not due to bent rim it can happen when the steel belt inside the steel belted radials gets damaged. Mine had this problem(indica). wobble only at slow speeds. Change of tyres fixed it.

As for your second question the mechanism is called hydraulics.

Yes my 800 has this slow speed thing.... though the wobbling remains almost same till 140km/h....
Any specific concern driving with such wobble?... coz the tyres are still almost perfect.... don't want to change now!... (MRF ZTVS)

tsk1979 · 10th February 2006, 12:07

This steel belt bending will not cause high speed wobble.
So if you get Steering wheel vibration then its certainly bent rim or balancing issue, if you get bouncing(your dashboard starts vibrating) its bush kit.,
Then there is gentle sway also when front Dampers give up. Your car will gently go left and right at high speed. So when you are travelling a straight line, the car will be roaming on the road.

SLK · 10th February 2006, 18:08

OMG!...
See the rims are almost fine...
but there is slow speed wobble and the balancing takes in HUGE weights.

>>So i'd say something is surely wrong with the tyres!
>>Then there is big time dashboard vibrating.... so bush kit!
>>And the car actually sways left-right at high speeds!... so dampers gone!

Thanks for the info!, now I guess its in trouble!

adit1329 · 10th February 2006, 19:30

what is the year of manufacture of the m800?
what is the mileage on the car?
have you rotated the tire regularly?
what is the condition of the tread on the tire?
is the suspension fine?
alignment?
balancing?
there are some more on the list, but if these are checked rectified, then the wobbling should have stopped.

SLK · 10th February 2006, 20:31

what is the year of manufacture of the m800? - 2000 (DX)
what is the mileage on the car? - 60k
have you rotated the tire regularly? - Yes
what is the condition of the tread on the tire? - 60% gone... (uneven wear? - yes but not in the normal sense - here it looks like every alternate block on the tread is wearing -funny?) (i'll see if I can get a pic tomorrow)
is the suspension fine? - no rattling from the suspension
alignment? - fine
balancing? - fine but takes toooo much weights ...

Have complained on quite a few services.. but they don't seem to get it!...

Also even when the car is parked the steering is lighter to the left side than the right.

Never dedicatedly followed up with maruti as this car is never used on highway and I don’t drive it.
