Recommended Posts

i was wondering if anyone else has this problem... when ever im on boost and i go over a bump in the road my rear wheels will bounce but un evenly and it cuases alot of shakes noise and discumfort not to mention the car doesnt like it much either

i was thinking it might have something to do with my LSD or rear suspention not sticking the wheels to the floor hard enough ..

please help

Seems to be a very common problem on R32 4 Doors with stock suspension

Easiest way to fix this would be to get yourself a thicker rear swaybar, and also some solid rear cradle bushes..

should stiffen your rear end up

Shock absorbers control the vertical movement of the wheels after the spring has been compressed (by a bump). What condition are the shocks in? You could try the old bounce test, push down on one side of the rear 4 or 5 times rapidly, and then release. It should retun to normal height without bouncing again. If it bounces its new shock absorber time. I would check the front as well, if the rear is stuffed, chances are the front is too.

If the bounce test looks OK, then my next guess would be rear subframe bushes. Have a quick look around the 4 bushes, marked in the following picture with the green dots;

What you are looking for is signs of leaking silicone, sticky goo and split or torn rubber.

Hope that was of some help

:D cheers :D

Also another thing .. this only happend if im excellerating over the bumps if i roll over then no matter the speed its fine

The tyres are transmitting the acceleration and twisting torque, shocks and bushes are both relied on to hold the torque.

:D cheers :D

i took my car out for a hard thrash last night and doticed that my car is tramping a lot more now. But ive noticed a little clicking noise now, when i ease off the clutch i can hear a clicking noise coming from the rear, its like with each revolution the wheels do it clicks. (the sound is kinda like if you have a rock stuck in you treds... but there is no rock in my treads) would this be related to anything i have been worrying about.

please if someone could help me ... if i were to take my car to a suspention specialist like Heasman at Tempe would i get charged an arm n leg for them to change my bushes or should i figure out how to do it myself

Is it difficult to replace the bushed highlighted in green as mine neet be be replaced (one has started leaking)? Are these the bushes replaced when fitting 'pineapples'?

Thats cool as the existing ones look like a hydraulic press job. Hopefully they should get rid of some of the tramp that the car gets occasionally.

Do the pineapples provide enough reinforcement to hold the subframe if the origional bushes are or even worse WERE leaking.

Mine tramps like nothing on earth, on the dyno standing next to the car I could see the left rear wheel and subframe attached pull forward.

I'm about to throw a set of bushes through the front and sort out the subframe bushes, Sk you will receive a PM shortly. :P

Noltec do subframe bushes for the R32's, they can be had from UAS for ~$190, but as mentioned are a pain in the arse to get out for the usual home mechanic.
