[DeTomaso] Front upright question

Mike,
I cleaned up the debris deposited when the origin bearing race spun dry on the spindle and it didn't look great, but useable. Install new bearing/adjust properly, but that outer bearing keeps getting loose and wearing away more spindle matetial. First set of bearings held up for several years, but getting worse now.
The surface is significantly metal fatigued from heat and impact of bad bearing. I serviced it before I drove the car other than a test drive when purchased, but was too late as the damage was done. I will take pictures when I have it apart.
I do track days with slicks and really don't want any potential for a catastrophic issue or just spoil a track day if that loosens up again at the wrong time. I have a good spare to use as I don't have time to repair this now.
If someone needs it please let me know.
Regards,
George

George,
Honestly sounds like a non-problem to me? People genuinely damage spindles by hitting curbs etc (crashing) and bending them. With the global supply of spindles being so low, I would argue they should be preserved for those who actually need them. Or, if you elect to change yours, you should make your old one available as it sounds perfectly serviceable?
Pictures would help here...?
Cheers!

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. :(

Mike,
I cleaned up the debris deposited when the origin bearing race spun dry
on the spindle and it didn't look great, but useable. Install new
bearing/adjust properly, but that outer bearing keeps getting loose and
wearing away more spindle matetial. First set of bearings held up for
several years, but getting worse now.
The surface is significantly metal fatigued from heat and impact of bad
bearing. I serviced it before I drove the car other than a test drive
when purchased, but was too late as the damage was done. I will take
pictures when I have it apart.
I do track days with slicks and really don't want any potential for a
catastrophic issue or just spoil a track day if that loosens up again
at the wrong time. I have a good spare to use as I don't have time to
repair this now.
If someone needs it please let me know.
