Loud clunk/jolt on extension
I'm having an issue with a loud clunk from the front end when going over larger bumps in the road that extend the suspension.
I first installed the OME HD lift with Bilstein struts in the front and Bilstein 5125s (if I recall?) in the rear from Kolak. I wanted 5100 series Bilsteins because I had them on my WJ and they rode like an absolute dream, and Kolak said they could be fitted to the rear with a couple washers.
Long story short, I couldn't stand them in the WK. The ride was extremely harsh; nothing like they were in the WJ. I eventually switched to the OME Nitrochargers like I should have gotten from the beginning, and they ride so much better.
The switch to Nitrochargers fixed most of my problems except for the clunk from up front on extension. I know what the loose nut at the top of the strut sounds like because I've already been through that the first time around, so I'm pretty sure that's not the problem in this case. I would describe the noise of the loose strut nut to be a hollow knocking over smaller bumps and road imperfections, but the noise I'm having now is a much louder jolt, and it only happens when the suspension significantly extends. Going over an expansion joint on a bridge with a steep drop-off, or going over a speed bump too fast is the easiest way to get that noise.
Could this just be the shocks hitting the end of their travel or something? UCA hitting the end of the ball joint angle? I'm wondering if JBA UCAs will fix this, but I keep reading that their biggest benefit is to get alignment back into spec, not necessarily for more clearance over OEM control arms.
