Just won an auction - M1088A1

Fleetpride or any other Meritor dealer. Part numbers are in the -24P TM

There are 87 mentions of seal in that TM and I'm not smart enough to figure out which part number I need

OK, I got it. I was in 24P-2 and the info I need is in 24P-1

Ordered at Big Mike's Motor Pool

Thanks VERY much for the help and please excuse my momentary stupidity. I am learning, slowly . . .

Tires leaking air - I've got two "new" 2023 tires mounted on the front. The CTIS valves definitely leak, new CTIS assemblies are supposed to arrive today.

Meanwhile . . . without the CTIS mounted, with only the tire valve stem with valve core inserted, both tires are leaking slowly. Down from 50 PSI to 10 PSI in 5 days.

What might I have done wrong in the assembly and inflation of these tires? They both have new O-Rings and Valve Stems.

Soapy water?

Did you use lube for the beads and the o-rings?

I did not use lube. What lube should I use?
On one of the tires, soapy water shows a leak around the valve stem. Did I break the stem? Or the rubber seal on the wheel is not down tight enough? I'll obviously need to take that tire apart

I just ordered Dow Corning Molykote 111 - hope that's the right lube

Dow 111 is amazing stuff and you should have a tube anyway. But it's not right for this application. This is what I landed on and have used on all my tire installs with zero issues:
