Gday guys, I have just finished fitting a set of tein coil overs into my R34 GTT. Went for a drive and noticed a knock from the rear.

I just went over all the nuts n bolts to make sure they are tight and everyting is.

Just wondering if anyone has had something like this before and knows what it could be??

Thanks guys!

Ok done a bit more reading.....

When I fit the new coil overs I didnt refit the metal plate that was between the strut and the body in the rear as the new ones are damper adjustable so didnt really want the adjustment screw being covered up by it!

Could that cause the knock?

<br />Nah the boots empty. I guess ill just have to keep playin around with them until i find what it is!<br />

is the suspension brand new or 2nd hand?

when you jack the car up, can you move the rear wheels up and down easily? i had this problem, i could just move the wheels up and down on the shocker. i had to get it refilled

They are 2nd hand....only done 10,000km tho supposedly! I put the metal plates back in the rear, (the ones that go between the strut and the body) and it hasnt really made any difference. Bugger.

Im hoping that the shocks arent stuffed in them already!

sorry forgot to mention daz, i checked for movement with the car raised and there is none.

thanks for your help so far guys

you said they were new..ha

well if theyre deff second hand then that knocking will most probably be your pillowtops. they are worn. i have used teins and my right rear and front knock over rough bumps. not much you can do really except replace the tops. when your in the back seat or boot jump up and down to work the suspension on whichever side, you should be able to hear the knock then.

Ok...this might be a longshot but it worked for me with my brand new set of teins...jack the rears up and spray the coil springs with WD40...try this before you do anything else to it. Let us know how it goes...

Thanks for that nismo, I was actually thinking about suggesting if anyone thought that might help, but thought i'd look like a total knob hahaha.

Ill give it a go and let you know what happens!

The thought also crossed my mind that the noise could be normal as i've never used coil overs in any of my cars before!

Cheers for all the help guys!

I am gaving the same issue with my 2000 Stagea.

Car was imported with Teins and is getting worse. Rears are really bad and giving me the S*its. Have taken to local suspension shop and they have no idea.

over speed bumps they are smooth, only over sharp bums they are knocking.

Will keep track of this topic lol

my brand new D2 coil overs knock in the front the odd time if i hit a hard or deep bump, but for mine its a knock being caused by the shock 'topping out' on its recoil...sounds rough but i dont think its hurting anything

      AC Compressor

      Lots of this, and in older cars, AC is generally controlled by the AC knobs and programming, and the ECU reacts to the load. Modern cars, the ECU controls kicking the AC on/off at the AC systems request so it can be prepared for the engagement/disengagement.

      Sadly, it won't happen. The AC controls in our cars are essentially on-off. Whereas the AC in new stuff is more a case of variable displacement compressors giving infinitely variable output.

      AC Compressor

      I don't think anyone did. But it still made me consider. For me personally it wasn't clear whether the AC experience in my car was shit because it is an old system, or because it wasn't maintained. Looks like it may have just been the latter. I see some more modern setup being sold as an upgrade and I wonder whether it would make it drive like AC in a modern car. Where you don't really hear it or notice it. But maybe that's asking for too much as well.   Haha, stick it in a Nissan Cube and you end up with a driveable fridge I'm not doubting your experience. Just thought it was interesting to hear the AC technician's thoughts on it.

      Guess I should be hunting down one of these big ol ford units then for max flow ....  I've had fresh gas in mine and it was never as cold as it is now . The compressor could have been trash though, like I said I am one example with a bunch of unknowns.

      I don't know if anyone was seriously suggesting a retrofit of an Echo compressor in place of a more-or-less working original comp. You'd have to change the hoses at the bare minimum to do so, and that will definitely add significant cost. I had to get my hoses modded when I did the engine transplant and chose to use the Neo's AC over the even older R32 comp. That was startlingly more expensive than expected for what looks like a simple welding job, and a massive pain in the arse when it turned to have a pinhole leak in the weld too. The Frenchie's kit is for people who have next to nothing of the original system or have more than that but some of it is a bit shit and better off thrown away than salvaged. If you've got 90% of the system, you just patch it up. Mine is currently degassed because it apparently has a big leak somewhere. If I find it is the compressor, I will be looking to take my spare comp to a shop to assess and/or recondition, rather than contemplating a retrofit to anything off-brand.
