Hello all,
I just asked this over at my thread on Wheel Bearings, but figured I would ask here too.
I'm getting new drive tires today, so would like the shop to check and top of gear lube in differential while that close to it. What oil should I use there?
Thanks
Seb
Instead of adding I would drain it and put in new and check the magnetic plugs for metal. I would put in whatever gear lube weight the book recommends. Of coarse brand and weight will turn into a hot topic so be prepared.
I would change it too,It came with the GL-5 rated oil depends on temperature in the area some came with 75-90 W and some came with 85-140w the brand makes no difference as long as it is GL-5 rated I use the 85-140 W or 90-140w, it takes almost 5 gals to change,strange the stuff is cheaper in Gal jugs than a 5 gal bucket most of the time
Years ago (mid 90's) when I was driving my 40 foot '68 GMC Fishbowl around, I checked the differential prior to going on an 800 mile trip down the Oregon coast (round trip). A bunch of long slender and very hard steel slivers came out that were about 1 1/2" long. I immediately put the plug back in, filled it with fluid, buried my head in the sand, and went anyway. The trip went just fine, but needless to say, once I started having additional problems with the bus and with the bus not being worth putting money into (although we used it for about 14 years), I eventually junked the bus. It was my first bus, and I was younger then!
Thanks for the suggestions,
Yes, I will start to head in the direction of changing it. No pit or lift so driving up on blocks and cribbing is the solution I'm guessing.

If change all the fluids then you know what you have,I would have the B500 Allison serviced they last a long time if serviced, take it to a shop the filters are in the transmission and the bolts are easy to strip on the housing ,the B500 is a expensive item to replace most shops are $12 to $15,000.00 exchange with labor
