Hi, I am restoring my TR3 and am currently working on the front trunnions. I have a question for the experienced among you.

I have a new set of trunnions, the outside diameter is 1 5/16” (see pic)

The seal inside diameter is 1 1/8”, is this the correct size seal or does it just stretch to fit?

Thanks, your help is appreciated

Geoffrey

Really hard to put those suckers on after you install the control arms. <g>

The process that seems to work best for me is to stretch the rubber seals onto the thrust washer first, then smear grease on both sides and slide the washer onto the trunnion pin. When the control arm is installed, the seal will spread onto the trunnion body and control arm.

Then all too often, split and fall off in just a few years.
