Mystery noises after 2.5 in lift installed

Long story made short ( for now).

Just finished installing a full JBA 2.5 in silver package plus changed all the ball joints, tie rods and front hubs/ bearings. After a full alignment I'm driving it and it is okay on the highway but is making several sounds when hitting bumps. The most worrisome is a loud thunking/ popping sound coming from the drivers front suspension. Any ideas on what's happening?

Did you forget to tighten some bolts?
That would be the first thing I'd check.

? Was the upper control arm bolts tightened after the full weight of the vehicle was on the ground?

Just got off the phone with JBA, I think it may be that I torqued the UCA bolts in the extended position. If that doesn't fix it I'll disconnect the driver sway bar.

Other than that, how does it ride with the JBA's

I also changed from stock wheels/tires to Moabs with BFG KOs...so all I'm going to say right now is that it feels more like a JEEP and less like a nimble little SUV....probably because I don't want to scrap the wheel wells! :SOMBRERO:

Retorqued the UCA and all the sway bar items ( just to make sure)...then the sway bar didn't want to cooperate :banghead:

Ended up taking about a 10 mile test drive through varied conditions and then hit the road for a 12 hour drive to the mountains! The noise is GONE!

I will definitely be posting some pictures, but i wondered if I should do a full lessons learned write up also. ... :dizzy:

PS - put the old stock tires back on for the highway and the MPGs didn't look bad for the conditions.

Yes full lessons learned write up would be good I am looking into getting the same lift.

Im looking to do this setup as well, would love to see some pics of it! You are running the standard bilsteins correct or did you upgrade?
