Figured I would give an update to more or less help someone out if they have a similar issue. I took the trailing arm off and took it back to the gentleman that rebuilt it. He checked it himself and confirmed there was a ton of runout on it. He pulled it all apart and threw the spindle in a lathe to check it and all was good there. After putting it together and checking it 3-4 times and having the same issue he finally noticed that the spacer end was not perpendicular with the rest of the assembly. It apparently was not super obvious something was wrong. He finally found the issue when he started MICing the spacer. We’re not sure but maybe in the past one of the bearings had been spinning on the spindle shaft and chewed up the spacer, which he noted during the original rebuild and replaced the shaft. Perhaps and rather than fixing it properly way back when they just cleaned up the spacer where it got chewed and threw it all back together. That’s our guess anyways. You never know what the heck happened with these old cars sometimes.

Anyways he didn’t charge me dime for the work even though I know he likely had 1-2 hours or more in it figuring out what was outta whack.

Got the trailing arms back in and found about .003 of runout still. We threw the rotor onto a brake lathe and found that the remaining .003 was in the rotor.

So thankfully that’s settled.

 

Sounds like someone others in your area can trust and might like to know about. The fact that he took this on again until the problem was solved and didn't charge you speaks volumes about his work ethic and problem solving skills. Be sure to share your experience with folks in your area. He's the kind of mechanic we want to keep in business!

Good luck... GUSTO
