The only other thing I can think of is radius arm bushes squeaking but that's a remote possibility given the fact it increases with wheel speed but you could spray them with WD40 in a process of elimination.

I'll continue to rack my brains (that shouldn't take long given they are small ) and see what other possibilities come to mind. Do you have CDL?

 

France, I appreciate your help.

I have CDL but without the linkage. It is a 2000. I guess without it locked I will have no drive without the front driveshaft because there would be no resistance. Is that right?

I checked the spacers. They are tight. I also spun the front tires and, if course, the driveshaft didn't spin and I heard nothing. The tires spin freely.

I noticed that at slow speeds (in driveway) there is no squeak when my foot in on the gas. Then immediate squeak when it isn't.

I guess the reason I am resisting the driveshaft option is that mine is relatively new and has grease fittings top to bottom. I keep it greased and used a ton of it today everywhere then sprayed lithium grease on the joints and it didn't even change the pitch of the squeak. It is a LOUD squeak; not subtle at all.

It is a little hot here.

 

Remove the front drive shaft, lock the CDL manually and drive it to see if the noise is gone. If the noise is gone, you have found your problem, and get the shaft rebuilt.

 

Sage advice.

Engaged the CDL with the 10mm (<<< hard info to find so there it is, people) I removed my two year old driveshaft and drove. No squeak. I've never engaged my CDL before so that's good to know how to do.

So now to install my spare driveshaft and find a shop to fix mine.

As always, the forums are excellent. Thank you again.

I'm still going to order a multiple double cardan from Tom Woods... measuring the distance from face to face now.

 

Good call, AC.

 

The two above highlighted parts seem to be contradicting each other.
If you stop when see grease start to ooze out, that's not enough. You want to keep pumping until you see new grease coming from all 4 seals.


How high it your lift? Double DC shafts (a DC on each end) are rarely needed on a a Disco.

 

I "BELIEVE" his shaft blew, its in a newer post

 

I pump it until grease comes out but, until yesterday, I was using the same color grease. Yesterday I used red. I used a lot before the red came out. I assume I haven't pushed enough grease in before. So for the price of ignorance and some lowly grease, I screwed my driveshaft.

Lift is 3 inch springs plus 1 inch puck, settled back to about 3 inches (ARB bumper and winch, and very heavy spare tire).
