My 75 '40 has a 40 LC rear end with Dana 60 full floaters and an ARB. I had to fix some leaks a while ago and was a little zealous on the wheel bearing adjustment (I did not have a fish scale handy). I also did not put an adequate amount of gear oil in the thing.
I went for a test drive and ended up having to drive to Ft. Collins for a family emergency. As I pulled into the hospital the rear was "groaning." To exacerbate the issue I had to haul ass home from Ft. Collins to change cars while a helicopter took my daughter to Denver Children's hospital. I knew this was not good, and the rear end let me know it by really groaning as I pulled into the garage.
So, the wheel bearings are adjusted properly and the gear oil is full and I still can feel the rear end tighten up when warm (~1 mile drive). This is not the parking brake; I have already looked at this. Today, I took off the rear diff cover and inspected the ARB and gears in the rear. All looks well, but if I galled the carrier bearings I would not see it with just the cover off.
So, my questions:
1) I assume I should pull the axles and DS and remove the pumpkin. Agree?
2) Where should I take this thing for inspection? I can pull the carrier bearing caps but have not done this and will have to get some help so I think I should skip a step and bring someone the whole assembly.
3) Is there any of my RS friends that can provide some assistance. I have never rebuilt a rear-end so I am a bit out of my depth. Mechanically I understand how it works but don't want to experiment; I want it on the road.
Cheers,
Jeff
