After buying the TR6 I learned that the Differential Mounts crack on these cars. If they break, the differential can “spin” in the back of the car, making a total wreck of the car and perhaps me and anyone riding with me. Goodparts sells a kit to reinforce this mount.
I had mine done – not with the Moss (read the Moss article for details on the steps involved) or TRF kit, but a custom job. When they pulled off the differential, we discovered my right side mount was cracked. The crack had not yet separated into a complete break, so looks like we got to it just before it became a problem.
So we had it welded up, and reinforcement plates welded on both right and left sides.
Other work done:
– one trailing arm had the bump stop broken off – drilled out the hole and helicoiled it to replace the bump stop.
– urethane trailing arm bush set. Mine were a mess
– the 4 rubber plugs in each trailing arm were replaced. Aluminum does oxidize when water gets in there – dumped a significant amount of white powder out of the arm that had the worst plugs. Moss had best price at four 7/8″ plugs for .75 each and four 1 1/8″ plugs.
– Also the right rear shock link was broken, replaced both at about 25$ each – (TRF part numbers) 141464 rear shock link (did both) and TD812 hub to trailing arm stud (did all 6)
– Installed Goodparts adjustable trailing arm set to solve a camber problem on the rear tires.
