Outer Limits 4x4 Board

hi all

just put in a 2" lift in my patrol, lovel springs (HD rear) and dobinson shocks.

when ever i go over a bump on the road the rear passenger side seems to jump, it makes the car shake

what could it be?
i wouldnt think having heavy duty springs in the rear would do this.

LWB or SWB?? what do you mean "jump"?? does it have bump steer? how is the steering dampner? are the bushes on panhards and radius arms fine? what about the tierod? trailing arms, are the coils and shocks 2" raised? are the shocks topping out?

more info and maybe we can help

he said LWB in the title

Felsy visit you local shopping centre and play with the speed bumps, thats what I do sometimes to nail which corner or side has a problem compared to the others. It's possible to line the bump and car up sometimes so that only one wheel at a time hits the bump great low tech device those bumps

has also stated which corner problem is,Tiny u should read before u post.

all bushes fine.
had a mate look at my car when going over a spoon drain and speed hump at 5kmph, when exiting the drain the LH passenger side wheel leaves the ground and the car tips down to compensate for the wheel being in the air, and thats only going 5kmph!!!!

tried it going a bit faster, about 10 - 20kmph and it still did the same thing but the other side left the ground to but only a bit.

must have brought faulty shocks!!

must have brought faulty shocks!!

Sounds like it!

How tight did you do the shock rubbers up? Tight can cause problems, I noticed a big improvement when I backed mine off. Not saying this is your problem but it might be worth checking.

yeah i checked that the other day and i put a little more rubber lubricant on it

does any one have dobinson shocks for a 2 or 3 inch lift? if so what is the part number off it,
im not getting full suspension travel, (tops out easily) just wondering if i have correct shocks

Yeah, need a measurement from centre of eye to centre of eye when the shock is extended. Also are those coils blue?

yes their blue lovel coils, i brought the lift kit off you last week

measures aprox 660mm eye to eye

i swapped the shocks from left to right, and one of the shocks is definately faulty, my wife wont drive the car with how its driving at the moment

Extended lengths are correct, so it sounds like one of them is valved too stiff. This is a 1st. Do you think the good one is valved too firm for your liking also. Maybe a shock with softer valving would be suited to you better such as EFS shocks.

So does anyone want a dobinson shock valved very firm? Going cheap.

the good shock seems ok, hard to tell with the faulty one playing up

Unless you change your mind, I will send a new Dobinsons shock Monday.
Send me an email of your decision.
