Re: 4H for 2 Hours at 65 MPH
The binding is just a symptom of the front CV's in 4WD

Re: 4H for 2 Hours at 65 MPH
Thanks,
So are the CVs worn out or can a guy needle some grease into them or...? I see there are 4 CVs, one on each end of each shaft. I am going to price out a couple of new shafts, and compare that to replacing the CVs on the old shafts. I will check my local APS and compare to online suppliers. I figure both sides have to be done?... because the binding occurs when backing up left and right.

Re: 4H for 2 Hours at 65 MPH
I don't think replacing them will do anything. The binding is just a symptom that occurs. Low speeds with the wheel turned will cause what you felt.

Re: 4H for 2 Hours at 65 MPH
Had a conversation similar to this on a forum (this one???) a few weeks ago.
It's not the front-axle CVs that are binding, it's a transfer case effect based on the front wheels turning a different radius from the rear wheels. Odd that you only feel it in reverse. Mine does it forwards and backwards. You're going to be inspecting the brakes anyway; it's worth looking at the rear shoes to see if there's a problem. In the olden days, the park brake was moderately effective forward, less-so backwards. The drum brakes were of the duo-servo (self-energizing) design, and they energized better forward than backward. My 1/2-ton used twin-leading-shoe brakes in the rear until I crammed a 3/4-ton axle under the back. The bigger axle uses the duo-servo design.

Re: 4H for 2 Hours at 65 MPH
I would check all the drive train fluids for condition .
transfer case could be making noise,.. |
