I googled RAYBESTOS 88PG.

I know the Chrysler part # is 4026636 and Bendix is RAF88.

The NAPA part # was SS88 but now that doesn't work.

Looking for the seals myself now. I see that some have the extra lip, I assume to sling oil in case of failure.

BTW, I bought one of the cheap torque multipliers on Ebay; OMG is it easy. You could easily remove the nuts with one hand, or snap them off tightening...

Yes, I believe the torque multiplier method is the easier way to go!

I just Park my 5 ton next to it and use the robotool. I wish they made these in 12v...

BTW, from the look of this

the axle is actually different than mine; the 71 has 3 bolts top and 3 bottom - not evenly spaced.
The self adjusters would swap!

The evenly spaced bolts would allow many of the new aftermarket disk conversions.

just a little fyi, make sure you "re torque" those lug nuts after about 100 miles or so and then again after a few more hundred miles. they WILL loosen up ! whether from a little dirt or alignment of the wheels as they roll. after 20 yrs and 3 sets of tires i'm speaking from experience.

I'll bet. I bought a torque multiplier, which every truck owner should carry, so ~8lbs input is 480 output, easy-peasey.
I also read some industry reports that excess paint on the wheel-hub mating and under-torquing are the main causes of broken lugs and lost wheels. It is the friction of wheel to hub that holds the wheel on, not the lugs per se.

I also discovered that I'm shopping for new tires. The Michelins have cracks on the inside sidewalls and are 10yo.

I'll also check the balance of the hubs while the seals are off and the bearings wiped from grease. It is actually a FSM mention for tires, and I found the right front hub was way out.

The bearings are so smooth that a 9/16" nut will cause the 50lb drum to turn if you tape it to one side.

I've had one front drum out of balance for the last 20 yrs. any one know of where in new England they can be balanced ? I've been attaching weights till it gets close with the wheel off the ground. not perfect but it took the low speed wobble out. my tires dry rot before they wear out anyway.
