Anyone have any issues with this? Have them in the E36 and all was ok. Slight noise when turning left to right. Assumed it was mudguards or what ever so. Removed them when putting in new mounts the other day. The sound has gotten worse since and sounds like the springs are hitting off each other is the best way I can describe it.

I will have a more detailed look when I get a chance but we thought it may have been drop links as well. From a quick google this seems to be a common issue. But there are no real answers being given. I'll check the top nuts as I hear they can come loose if not tightened when the car is on the ground.

Anyone?

Thanks.

I had an knocking issue on one front coilover. Top nut on one coilover was getting lose every week when driving I replaced the nut and problem was gone. Also I would suggest to check drop links as they can cause same knocking and annoying noise.

when u put on the new top mounts and locked the top nuts down did the coilovers spin (rotate) freely...?? or were there locked up tight to the bottom of the top mount...???

if there were locked up tight they will make noise when turning and will bang....

i put an extra washer between both the top mount and the coilover.... it allows more direct contact to the bearing in the topmount and allows the coilover to spin around freely when turning, as the coilover is steering on the bearing and not locked up to the rubber mount

also make sure the top mount nuts are good and tight....

that will sort the coilover noise if its still banging change your droplinks....

Got a chance to have a look myself. Bit in awe of the results I found now i must say.

Seems fixable.

Here's the links for those who have ruled out the top nut and drop links.

Now that is interesting. I had washers in the first time around like that and found they were causing more issues than anything noise wise so I removed them as with the JOM bumpstop they shouldn't be required but we all know how that story goes

Top mount was tight to the strut and not spinning freely.

Need to wait till the weekend before I can take it all apart and sort it.

you need to have it spinning freely if there not you get that creeking noise on full lock as its straining on it self.....its only a few mm the washer, but it does the trick.... joms being joms the build process well enough said.....

also good find on that link..... makes good sence.

Ah well at least it's not goin to be a pig of a job or anything. Another saturday playing with the car it is so.

oh and i also should have said the mounts we put in are evo top mounts reversed but surely a mount is a mount where jom are concerned?

i was going to say exactly same. i had same issue on one side only, took 2 washers as one wasnt enough, and people can only see that when car coil is under the load, when top mount is just sitting there it still may be spinning free without touching, but when under load, it starts roobing, and then just shoots back like a spring

Hi there, sorry to necro this thread - where exactly do the washers sit once the coil is off? Recently bought a 36 with these on and I don't see a washer to speak of
