...I've had this on and off since I got the car (NA) 3 years ago. At first I thought it was disks so I replaced them, but it still juddered once the pads had settled in. Then I noticed that it went away if I replaced the pads, but when they were half worn, the judder was back. I'm told that the calliper pistons get corroded at their midish point so last weekend I dismantled them and cleaned them uo - they were like new - and replaced all of the seals (kit off this forum). Bled the brakes and all's well, apart from the fact that under easy braking. I still get the wheel wobble - but no where near as bad as it was.

 

Both tie rod bushes seem ok, Pads are ok, disks look ok - so I'm stumped.

 

Anybody got any ideas where I should be looking next? The car stops ok, just this annoying wobble of the steering wheel and judder from the brakes.

 

Obviously the new seals and dismantling, rebuilding has had some effect, but I though it would cure it.

 

Any ideas would be appreciated.

 

thanks

Could be wheel alignment - worth checking... Have you correctly torqued the wheel nuts???

 

CheerZ,

It's also very important to have the wheelnuts torqued to factory specs with a wrench (not pneumatic)

...wheels balanced, newish Pilots all round, laser aligned and torque wrench tightened.

 

The judder is felt through the steering wheel more than the car. When braking lightly the steering wheel moves left to right rapidly. When braking hard all's fine.

 

...any more ideas?

 

many thanks

Could be your flexible brake lines to the callipers they can brake up inside and block but will normally have a job to bleed the brakes with this problem, also did you replace the pistons or just the seals just cleaning up the pistons dose not always work. Could also be your tyres gone out of shape bit of a long shot thou.

You say you have checked your tie rod bushes have a good look at them mine was terrible under braking till i put poly-bushes in them.

Good luck:D

Sounds like the turbos.................................sorry its just they get blamed for everything else

...I'm coming round to the idea that it might be the tie rod bushes. I replaced one when I got the car 3 years ago. The older of the 2 looks ok, they both do, but do you know if they progressively deteriorate or just fail suddenly. Again any advice gratefully recieved.

 

thanks

I have the same problem and I have changed the discs, pads, fluid, put poly bushes in, wheels balanced.

 

I don't confess to be an expert when it comes to Z's suspension and the only thing that I think it could be is any other front bushes that have perrished or that are worn. Could this be the case?

Jack.......It really does sound like your tie rod bushes.

 

So have you got one poly bush and one regular? Just replacing one wasn't such a hot idea I don't think. It is bound to be these.

I replaced one rod when I got the car - replaced it with a Nissan original part, not poly, so both are the same. The ant-roll bar bushes are looking a little shot - have done for a while, but the MOT man never says anything about them. As for the posibility of other worn suspension bushes - any recommendation as to how I detrermine what's worn.

 

again thanks for the help...
