Another warm weather day in Princeton, amazing its in the 60's (F) in February!
Brought some of my metal painting outside as it was so warm (although windy) using my son's basket ball hoop as an ideal place to hang metal bits for spraying.
Went back into the shop to continue disassembly of the left front hub, stub axle, lower trunnion assembly, and bearings. As I was disassembling I noticed a fair amount of play in the trunnion. Odd I thought, why would that be. I carefully unscrewed the trunnion and cleaned off all the grease. I could not believe what I saw. The thread on the vertical link was completely chewed up. Almost disintegrated. I could not come up with a logical explanation to myself of how that would even happen. Bad wheel balance and driven for an extended period of time? No grease? Lower control arm bent and causing unusual loads on the trunnion? What could cause this on a low mileage car?
As I have mentioned before, some parts of this car demonstrate it wasn't driven very much, other parts are completely shot. I wonder if the first guy that owned it only autocrossed the car and put huge loads on it without understanding any normal maintenance requirements? Who knows.
Luckily I bought a parts car several months ago and stripped the front suspension, gear shift tubing, engine and transaxle off the car (sold the chassis and body). I went right to my "spare" left front wheel assembly and took everything apart. Good news, the entire assembly is in perfect condition. Now I need to completely media blast all the parts, paint and then reassemble with all new bearing and bushings.
