Re: [Amc-list] Looking for an M20 to fit a Spirit near Seattle

[Frank Swygert <farna@xxxxxxx>]

Good luck finding a M20 to fit! An American M20 should be close enough to the same width. 

That vibration sounds like a wheel bearing in the rear axle, not a pinion bearing. The outer axle bearings will go first since they carry all the weight. Pretty easy to change and inexpensive, just need a hub puller or hydraulic press to get that hub off. Oh, and a big torque wrench to tighten it! The local big-rig guys do it for me for a token charge, but the owner's a friend of my brothers and I make it easy (remove center cap so wheel doesn't need to come off). When I was away most places would do it for a half-hour charge or their minimum charge, and a couple only charged me a half-hour when an hour was the minimum since it only takes 15 minutes (making it easy was the key!). When I didn't have access to a press I would pull the axles and take them to the local machine shop and get the bearings and seals installed then put them back in. Can't recall price, but was very reasonable -- usually dropped them off one afternoon and picked them up the next.

Looking for one to overhaul, but a reasonable priced good runner would be okay too. The current M15/D35 has a pinion bearing or something going out. After driving 55 mph for awhile, it will suddenly start to vibrate like a bad Ujoint (already checked that) and it feels like I'm on a rumble strip unless I slow down.
