That's a steal! i almost want to buy one just to try it out!

...but i'm going to change fluids first, and check for shavings.

 

Yeah, I posted it just in case.

 

That's a good point.
Drain the front diff and if the oil is BLACK then there is a problem.
Oil is still brown, then OK.

 

Probably is the evil CV.
That's why Discovery I may be actually better in this area with swivel *****.

 

Yeah, it's funny we don't hear about bad cv joints. I haven't been here that long, but I don't think I've ever heard of anyone having cv joint issues.

 

1) Have you checked the radius arm bushings ? Check them all but look close at the one that mounts right under the passenger.


2) Check the 2 transmission mounts.

3) When you had the drive shaft off did you check the flange in the T-Case for play? There is a bearing that the flange rides on that can fail. You can normally move the flange by hand if is has failed.

Thanks Jared.

So next things on my list to do are:
1. change and check Diff fluid
2. change and check tran fluid
3. check radius arm bushing (this seems like a good possibility)
4. check transmission mounts
5. check transfer case flange for play (though i did not notice any when i checked, i did not specifically check it)

 

The first post stated the thump is "in rhythm" with speed of vehicle. Seems to me that a bushing wouldn't do that, save for a transmission/engine mount.

I would move #3 to last, and #5 closer to the top. Just my .02.

Also, just thought of this. Leave truck in neutral, Transfer case in neutral, parking brake off, and try jacking up the suspected wheel (The truck may roll off the jack. Be careful!!! Make sure you're on level ground and chock all other wheels front&back). That will permit the suspected drivetrain section to rotate. Give the wheel a good spin, you may hear your noise. Then try moving the wheel quickly forwards and backwards while listening. The change in direction should highlight any gear slap or flange issues.

 

Engine mounts are another possibility that just occurred to me.

 

If it were engine mounts, wouldn't i feel it even when not moving forward?
