[DeTomaso] Front upright question

Thanks Mike and Forest!

My original is beat up from lack if maintenance by a previous owner. When I got my car the wheel bearing was shot and had a ton of lash. The spindle surface under the outer bearing race is fatigued with small chunks missing.  I will save the original. Would rather replace it now as I don't have time to deal with repairing it.

Anyone know of a torque spec for those arm bolts?

Thanks again,
George

Yup, that’s exactly correct. The 1971 cars used different spindles that incorporated the steering arms and were side-specific. Then they used spindles with separate steering arks that were nominally identical except the driver’s side (I think?) was reverse thread. Later they did away with that and both sides used normal righty-tighty. That meant the same spindle was used on both sides.

Spindles are rare and precious, and are worth saving if at all possible. Why are you changing yours? Definitely keep the old one even if it’s not perfect.

Last time I was at the De Tomaso factory I saw a huge crate holding hundreds and hundreds of spindle forgings. They were covered in light surface rust but extremely useable. They just needed the finish machining processes performed. I hope Wilkinson was able to recover those and they didn’t just wind up getting scrapped. :(

   My original is beat up from lack if maintenance by a previous owner.
   When I got my car the wheel bearing was shot and had a ton of lash. The
   spindle surface under the outer bearing race is fatigued with small
   chunks missing.  I will save the original. Would rather replace it now
   as I don't have time to deal with repairing it.
