The bushings in my 5100s were worn out by 20k miles. I replaced tgem two weeks ago with ones from whiteline. They are already showing signs of wear. The bolt compresses tgthee bushing on the top an ruins them. Any thoughts on why?

Can't see the photo, but are you referring to the strut post mount bushings? (the top ones that go in the coil bucket)
If so, You are not supposed to crank that nut down all the way. Only so that is gets snug or something like 15 ft/lbs if I remember right.

If the lower, just because the bushing is sagged (bolt not centered) doesn't mean its bad. It is only considered bad if there is physical damage.

Thanks.

Its the bottom. And yes there is sign of physical damage after only 2 weeks of running them.

Are you torquing the bolt while the truck is on the ground supporting its own weight?

If you are doing while up in the air still under full compression that bushing is seeing lots of twisting motion and could get damaged. I had asked PRG Greg once why he doesn't offer any titan swap options with a lower bushing when I was doing research and his answer was that a t swap provided too much rotation on that bushing and they would fail quickly.
Are you running this on a t swap? If so, are these Frontier of Tundra shocks? The Frontier ones have a much smaller diameter than the tundra ones and can not handle as much twisting action.

Iwill try torqueing them down with a load on them. Thanks!

Try posting the picture again. Even a link from your facebook account will show up here.

Do you run a spacer on top of the 5100.

Another thing to consider is that some of the OE lower strut bolts are tapered bolts and can sometimes punch bushings easily - especially on coils. Somewhere I found the proper diametre bolts listed and replaced both of mine.
