Rear diff problem.
The trucks a 93 F-150 with 67,000 miles on it. I kick around with
6,500 pounds on his back on a regular basis.(3 or more times a week) I think the diff is a Dana 44 but I've not crawled under to
I.D. it yet.
When shifting from park to drive I get the same fealing as a
warn u-joint, or an high idleing engine. MT or loaded. At light
acceleration I can hear an instant click sound.
Had a flat on the rr while loaded. When I finally got the truck
in the air, I could feal a lot of play in the axle area when
pulling on the drum. I could also hear the click sound.
What the heck is is it? Can it be repaired? Don't worry about
it? Or get a whole new diff.
The milage is correct and the service has always been well main-
tained and documented.
Thanks to any and all who reply.

Rear diff problem.
I have an older truck ('85)with the same problem. I don't know what brand axle it is other than it is an 8.8 with 3.55's. The U-joints are good but I had my wife put it in drive while I looked under and I could see what looked to be a good amount of play in the rear diff. Someone mentioned that you don't want more than 1/8th of a turn when putting it into drive. I haven't checked to see just how far it's turning. I have quite a bit of mileage on mine and my belief is that it has to much play.
I was going to swap it out with a nice LS diff. but if that turns out to be to much I'll take it in and have it readjusted.
