Thanks Toddie.
Everyone should watch this video and think about your tail shaft and uni joints. This is Very. Very Important! Check this out and have a look at yours.
Very good Info, thanks Toddie.
would double cardan joints eliminate the vibrations though ?
That's one of the reasons why guys with Shorties and big lifts have to fit a double cardan joint.Quote:

I thought it was because having two joints makes it stronger due to less angle not the vibrationsQuote:

On this subject how does one check that their tail shaft is in "phase"
Match the uni joints at both ends. Sit the both either vertical or horizontal at the same time when fitting the tail shaft.Quote:

Surely that won't work. As the two ends of the tail shaft have a splined joint you can't rotate.. Otherwise the tail shaft wouldn't work.Quote:

yeah come one MR! get your story straight mate!!!Quote:

The only way to align the universals so the spigots are identical position either end is to rotate shaft on the splines. You may have to have your tail shaft rebalanced.
And if you try to put the CV joints?
Ive been getting a real clunk in the drive train recently and got under the y60 shorty today for a look.
the Diff backlash was clunky and so was the transfer gears but what surprised me was the sound in the drive shaft spline.
I greased the spline via the nipple and the clunk is gone now.
Just goes to show that even if the rear diff has wear in the spiders, that spine can be the actual problem.
Id say the drive shaft spline is probably worn out though.
Purchased a good second hand front diff head for it today as there was a tad too many big bits on the magnet last oil change and will do the rear as well as the drive shaft.
Good thing about these trucks is that the parts dont break the bank
Do not click on the previous posts link!! Pricks are getting clever.
Cheers Craig i was just sorting that out. Just report them mate. All good.Quote:
