Sup peeps, I drive 95 s14 with k-sport slide controls and cusco arms, so I have this kinda pop/thud noise on the driver side rear i only hear it when the car has been sitting for a little while, ill go out to open the door and hear the sound if that doesnt trigger it then sitting in the car triggers it, anybody else had this problem, if so what should i be looking for? thanks

Sounds like something is unloading when you shift some weight in the car. See if you can take a look while someone else opens the door or sits in it.

When my car started making "popping" noises, i checked out my arms weren't lubed, so i lubed the bushings & hardware and the popping stopped. maybe that could help you

oh ok ill try that out, what kind of lube do you guys recommend i use?

...is there a spray kind i can use that works well??

AdrenalineS14

.... well hahaha i used WD-40 ill see how that runs :/

jr_ss

WD-40 will make your parts rust... Use a silicone lubricant spray, white lithium grease, etc... Now that I think about it, it could be your coilover springs too. They tend to twist on their seat as the spring is compressed/uncompressed.

For me, its almost always the coilover springs spinning off...

Hey guys.... lol sooooo im still getting the thud sound. So far i have jacked the car up removed both wheels sprayed everything with break cleaner, I let it dry sprayed everything with dry lube, cleaned the coilovers checked the springs checked the arms and all, everything looks clean and good, I have rear subframe collars not sure if maybe thats the cause, and also I DD this car and granny drive it. I shift gears at like 2500rpms or so and i feel as if the rear is lightly catching/thud(i have a nismo 2way) everytime i shift other than that the car drives smooth. i need help figuring this out! Im highly considering getting those parts shop max solid bushings what do you guys think?

And also make sure your springs are seated correctly on the perch.

Has your subframe had new bushings installed?

No, looks like the previous owner cut the bushings and installed some blue aluminium collars kinda doesn't look right... bottom collars aren't even flush against the sub frame wondering now if that's partiality the problem

jr_ss

Yep, I'd be looking for replacement bushings for the subframe...
