? for those with 5100 Bilsteins (clunking?)

260K miles on 5100s and still going strong. No clunking. Just install them correctly.

Proper test is to push the bumper down hard and watch for bounce.
 
78k miles on my 5100’s with no noises, they have done very well. I have mine set on the 1.75in setting in the front with a 1 inch bilstein spring in rear. I run 285s and take it on the beach almost every weekend. Thinking about replacing soon due to use/miles.

Installed my 5100's 2.5 years ago (12,500 miles on them), with Dobinsons 302s up front, spring cir-clip on the lowest setting, have 1" CornFed Rear Spacers, running 285/70/17 WildPeak ATW3 tires on TRD PRO wheels and they've been fine.
 
This will be a resurrection of an old thread here. About 45k miles ago I installed a full set of 5100’s on my ‘13 Trail. The front is set at 1.75” (3rd notch) with the factory springs and I have Cornfed 1” spacers in the rear. Over the last few months I have noticed a decent clunk coming from the front and rear. It was very apparent when a buddy and I were on some rutted up dirt roads just north of town as it sounded like something was very loose in the suspension. At this point I have been all over this thing and cannot find any loose fasteners. The front lower control arms are new (had the noise prior to this) and the upper ball joints have been replaced. All the bushings for the KDSS front bar have been replaced as well. There is no noticeable movement in the tie rods or ball joints when the front tires are off the ground. All the shock bushings look to be in good condition as well. Is it possible this is an internal issue with the shocks? What say you?

Just curious, did you ever find a solution here? I have a spacer installed, around 1.5" and get this same clunk/loose feeling when hitting bumps. Toyota recommended upgrading to the 5100s but I'm afraid this won't fix the issue. Going no lift might be the only option.
 
Sometimes things aren't tight even though they've been "torqued." This seems to be true especially w/ suspension components. Maybe it's the nature of rubber bushed connections, or not having the corner supporting its weight while tightening.

My best experiences have been to tighten any suspension component while that corner is supporting its own weight, then drive a bit, and lastly repeat the first step. Otherwise I've had "clunks" of various degrees for certain jobs. Sometimes I got lucky and the minimalist approach worked, but not always.
