Suspension Clunking Problem

[Steg33]

I've just put some new MDU coilovers (yes they're cheap stuff but it's just to get it back on the road for now) into my R33 GTST and they feel fine until i get to any kind of bumps/pot-holes and the like. Around town any sort of sharp bump is giving me a loud clunking sound that sounds like the strut tops are going to break through the towers.

When the car is stationary and i bounce it the shocks sound like they are topping out with a 'clunk'. My last HKS set started doing this due to a worm washer in the strut top joint but this stuff has never been used. I'll double check that there's no movement here and everything's tight.

I'm generally of the view that you get what you pay for but even cheap crap can't be this bad before it's even been used??

Any other ideas people?

The problem's still there at the moment so it's going to be a trip to pedders soon i think......

Anyone else used this MDU suspension or have any other thoughts??

I know who makes these coilovers, they are made in China at the lowest possible cost.....my advice is to get them out of your car asap before they cause an accident.

massive thread revival i know... just wondering if you ever found a cause behind the clunking noise?

I recently installed some new BC coilovers in my r33 and have similar noises, I think it may be dead tie rod ends/boots ?

You guys did make shore you tightend all bolts up all the way. a slighly lose nut could cuase the noise.

Mine has a busted ball joint in the rear. Makes a horrible clunk noise and drives like a forklift.

I have the back of the car on chassis stands ATM and there is about an inch of play in the back wheel.

Hey Peter, I was thinking along the lines of busted ball joint... I ordered new tie rod ends as mine were shagged, hopefully that will fix my clunk.

Do you guys find that the top pillow ball joints make the clunking noises, i know mine do, they are only HKS Hyper d's, i'd like to know if with new ones they will shut up, i had the rear shocks out and the pillow ball has a very small amount of movement( 0.5mm approx) when talking to some guys that rebuild and build coilovers they tell me this is normal, put up with it, they are not worn out???

Maybe what is described above is the same problem, mine just rattle over most sharper bumps, ie lots

Yes, pillow ball tops are sh1t for a street car...rattly, annoying and the bearings constantly wear...had Buddy Clubs in my previous ride, S15...drove me nuts.
