Driveshaft angles / lengths

[V8 Middy]

Had the lockers installed the other day and the guy at ARB pointed out to me that the rear driveshaft is under compression (ie. too long) but the front drive shaft is hitting the chassis cross member when the suspension flexes.

Its almost as though the whole transfer case should be mounted forward an inch to correct both problems but it is in the standard location now. Shortening the tailshaft only solves half the problem cos the front drive shaft only has 9-10mm clearance when the vehicle sits on level ground.

Suggestions to rectify this have included:

Raise the gearbox anything up to 60mm. (As the truck has 60mm bodylift)

Install a CV joint to stop the shaft hitting crossmember

Get out the angle grinder and take a huge chunk out of the cross member


If the current location of the gearbox is indeed original, I'm guessing someone must have seen this and corrected it. Venicle is 1988 MWB Landcruiser, 60mm body lift, 50mm spring lift

Thanks

I had a similar problem in my standard powered Hilux a while ago.

I think it came from the suspension upgrade although it doesn't explain the rear tailshaft being under compression.

I would get the rear one looked at and maybe shortened. I had tail shaft probs and was very happy with ORI. The reason for geting them to llok at it is if you just cut it you may shorten splines etc or not fix the prob properly on the male end of the tailshaft.

The front one you could get away with a spacer to correct the prob there, I think most places sell them now.

Hope it help.

My bit.

Thanks Busiboy. Where do I find this ORI mob (I'm in Melbourne)

Would a spacer create too much angle on the front uni?

Sorry forgot to look at your location.

They are local for me.
