So Im in the middle of replacing all of my bushings. Currently have my rear end out and just replaced the DTSS with solids. Now I see that the hub/knuckle has two more bushings. One upper bushing it feels like a hard rubber/solid and the bottom one is a spherical bearing type. Now since I have eliminated the dtss, I really cant imagine any movement between the hub/knuckle and the rear control arm. So my question does anyone sell solid delrin upper and lower bushings for the hub/knuckle? Or at least the lower to eliminate the spherical bearing? I've been searching online for several hours and couldn't find anything. I seen Aaron Cake's build, but I dont think he mentioned where he got them. My car is 87 t2.

 

no one makes anything to replace the spherical bearing. it's already solid... so it's fine.

you can replace the upper bushing with either another bearing from Supernow or an aluminum bushing from PBM:

thanks, I actually bought several parts from that site.

 

The PBM bushing works great.

 

Any benefits to replacing the upper bushing with the solid ones?
