Like the title says, after driving around on my Toby TABs for 8 years, I broke it all down over the past week. The primary purpose was to install DPI's new S/S trailing arms, S/S hard brake lines, S/S trailing arm brackets, and adjustable rear upper links.
Naturally, I was eager to see whether the Toby TABs had lived up to their indestructible reputation. They had. I found no deformation nor corrosion of any kind.
Upon reassembly, I realized that if I installed the TABs with the bolt-heads facing outwards, it would enable me to torque the nut rather than the bolt. Doing so would obviously promote a more accurate torque measurement for the joint since the friction created by rotating the bolt within the bushing and trailing arm would not factor in. I would recommend everyone install the TABs with the bolt-heads facing outwards for the same reason. I added two grade 8 nyloc nuts on each side (double-nutted).
I elected to torque the TABs to 60 ft*lbs, though I could not do so at the proper ride height because I do not own a four-post lift. Even with the rear wheels on ramps, some of the weight is unavoidably shifted to the front wheels, which raises the rear ride height from its resting position. Accordingly, I will advise the technician to de-torque and re-torque the upper rear link bolts and trailing arm bolts while the car is sitting flat on a four-post lift during my four-wheel alignment this week.
