Thank God - 2025 is Over !
​​​
My Plans for 2026 is going in a different direction. Since the assault on Dec.5th, I've had to re-think my future plans and especially the work I do. I find that it's getting harder to lift a AAM 11.5 Carrier ,( 90 lb. ) and install into a 1 ton truck on the lift. Since I'm only 74, I need to make every moment count. I can lengthen my days or shorten them. It's up to me.

Getting ready to Retire
2026
While driving, the gear oil flows into the tubes and lubricate the axle bearings.
Fact or Fiction
You Decide?
A RAM 2500 had a seized
wheel. He just did a brake job.
I Carefully Cut the bearing.
The spindle was saved.
This guy wasn't so lucky. He lost a seal on the highway.
A couple of days later, I had him back on the road making his money.
This is what I thought for many years. Then I was getting spindle replacement jobs for the 3/4 ton and 1 ton differentials. Usually the customer would lock up a wheel because the hub seal failed. But lately, I was getting jobs from brake shops and other repair shops. They Said the truck only had a couple of miles and the wheel locked up. First thing I asked, Did the mechanic tilt the differential to get oil into the bearings. The answer was always no. They never heard of that.
The oil level is either level with the bottom of the bore or just below.
The outer bearing always seizes first, because of its size, It dries out first. The inner bearing seems to always have a little oil on it. When the bearings goes bad, the axle starts rubbing the top inside of the spindle bore. The axle gets so hot, it finally welds to the spindle or just twists in two. Anyway, it needs a spindle.
