I've started my upgrades from a set of 17" wheels/tires + rear sway bar by TRD. That improved the handling some. 3 weeks ago I decided to add a TRD springs to this setup. Handling is even better now, but I'm hearing these popping sounds now all the time. Usually not when going on straight flat surface, but making turns, on road bumps, etc. Anyone experienced anything similar ? I wonder what could've possibly go wrong with the springs install to cause this? Thank you, guys !

did you install the springs? was there a rubber sleeve that was on the spring where it comes in contact with its mounts?

front or rear?

Installed at the shop. I can't really tell front or rear.

ok, just drove it again ... It is coming from the REAR and mostly when start moving from the complete stop, NOT much on turns and bumps like I said before.

Mine started making noise from the struts. After a few day of the springs settling the struts needed to be retightened.

what car/springs are we talking about ?

Went to the shop today and guess what ? The sloppy f#@k that installed the springs forgot to put back the rubber(bushing?) that holds the muffler in place :relief: That's what was making those misterious noises ...
I swear - one of htese days I'll get ____ed off and learn to work on my car ! :rofl:

...why on earth did he even mess with the muffler...

I have no answer on "why?" but it looked like he'd removed the muffler - that rubber thing + 2 bolts were not tightened correctly ...
