Very harsh over bumps and banging! - Retro-Renault

amdaman · 19th November 2006, 10:24 AM

Right, my car acts like it's got no suspension! Over some bumps it really bangs like the suspension is made of concrete or something! Could any of these affect it:

Valver shocks (it's a 1.4)
Tracking is well out
lowered 35mm
quite a negative camber
Wheels are quite heavy (215/17/40)

It was acting like this before the valver shocks as well. Some bumps are ok, others feel like i've got no rubber on my wheels and it really bangs on the road!

The wishbone bushes, shocks, springs and balljoins all seem ok too? Surely it shouldn't be that much of a harsh ride.. would gas shocks help?

Broken coil spring? i had a knocking on mine,turned out to be the ball joint,not sure if yours has an antiroll bar but if it does check the buses on that, check your engine mountings as well.is it only when over speed bumps or does it knock when setting off and stopping?

Sorry didnt see the spring part

everything you listed is the fault.

Ok cheers, I got it tracked up today and it's much better over the bumps, however when letting off the accelerator the steering wheel moves a bit but the car doesn't.. which is odd.

could be a lose/wishbone wishbone, balljoint etc or the rack bushes

wishbones seem ok, got balljoints ready to fit, no play in column, where am I looking for the rack bushes (obviously the rack but where abouts?) they sound like a bugger.

cheers.

2 big rubber bushes that gop between the rack and the subframe.

Ok cheers, i was testing it a bit more today. say i'm doing 30mph in 3rd, i put my foot to the floor and the steering wheel goes to the left about 2inches but the car doesn't go to the left, and if I let off again the wheel goes back to normal ... it feels a bit dodgy tbh!
