Vibration at speed onlt in 4H

[DannyBoy]

Hi guys, as the title says it onlt happens in 4Hand at a higher speed say 50km+.

Fron through the posts on here its leading to prob shaft but curious to why its only happening in 4H and not 2WD?

Cheers

I'd look more closely at the output shaft bearing on the transfer case. Specifically, slide underneath and try wiggling the prop shaft near the transfer case. If it's so tight a nun would be proud. it's probably a balance issue.

Of course, if the nun's upset, you might need a new bearing.

slid under and pressed against each UJ and at the transfer case section there is a little bit of movement and an odd noise.

Still confused as to why I would only feel this in 4H due to the front prop shaft spinning while in 2WD, my guess would be due to the additional load placed onto the bearing?

Mine probs moves probably 1- 2 mm..only just made 100,000kms no noises tho

im sitting on 72,000. are you getting any type of vibration because of that?

Nothing at all.i assumes it was like that from new.as its never done much hard work

 

[Old.Tony]

The movement is not good, under load is where you're actually trying to pass energy through it so that's when it'll react the worst.

Hopefully it is only a bearing. That makes perfect sense thanks Tony!

Cheers

Could be from my last outting where I ran it harder than any other time. But unsure where it has been from 0km to 54,000km as I bought it second hand.

This is the second TF output bearing issue inside the last couple of weeks. Makes you wonder if there's something about that bearing.

Please let us know how you get on.

Will post back once I take a good look at hopefully tonight.
