D2 drive shaft 13 degees with 50mm lift solution?

Just to clarify the rear shaft possible change. If I had to change the angle of the transfer case for the front to point down more it would lift the back of the TC up. This would than mean the rear shaft is on more of an angle to the rear diff. It I had to do this than I don't think the roto flex could handle the extra angle.

If Discorevy is correct that shaft speed is approx. 2350rpm at 100kmph than I'm only 5 degrees out rather than 7 degrees. To answer your question the uni's are buggered (grease overheated apparently) and the uni end caps started spinning in the yokes.

Back to the original question, has anyone attempted to change the transfer case angle? I'm guessing lowering the TC mounts won't work as this would tilt the TC backwards and increase the front flange angle. Therefore I'd need to either raise tc or drop both the engine and tc mounts. Don't like my chances of dropping the engine.

The alternative is to grease all the uni's and centre bearing regularly. But how many the cars do you hear of having to do this? Even though it is a good idea. With no lift and a standard shaft the uni's lasted 300k kms I'm assuming because the angles were correct. Rather than building a super strong shaft I'm trying to fix the problem if possible.

You're trying to solve an non-existent problem.
You have a 50mm lift. Slunnie and I are running 4"...
A Wide angle DC up front will sort you.

By wide angle do you mean a Tom Woods shaft with 1310 uni's and greasable centre?

You are probably right. But what is the cost difference between a Tom Woods shaft and a rebuilt front factory front shaft, 2 tc spacers and a D1 or RRC rear shaft?

I'd guess the later would be cheaper.

Tom woods is the go

Spacing the TC will bring the top of the fan towards the radiator, change the rear angle to even greater.

The D1 rear shaft won't be cheap not the flange..

The mounts are angled so lots of fab work on the TC mounts.

You can get a HD joint fitted to the factory shaft at Hardie Spicer.

And I don't run a Tom Woods. I run a similar, wide angle unit...

The standard shaft lasted 300,000 Kay's?????

Mine lasted about 130,000 Kay's.

Having been through this for a defender this week I was told by Hardy Spicer the centre bearing joint on their supplied DC joint was not greasable. HS wanted $609 for the DC joint (part only) before labour to weld to my old shaft plus balancing.

For me it was cheaper to buy a Tom Woods shaft than have mine rebuilt locally. TW shafts have a greasable centre ball joint which is prone to failure if operated in a dirty environment ie mud.

Some front prop shaft options and prices. Tom Woods doesn't advertise price, as far as I can tell but have e-mail him and waiting on a response.

300tdi / TD5 Front Double Carden ULTRA EXTREME Wide Angle HD Prop Shaft GL-DC-ULTRA-EXT-605

Double Cardon Propshaft 610

TFDC610 - Double Cardan Propshafts

Tom Wood shaft is US$399.00 plus approx. US$185.00 Freight.

Shaft AU$ 560.00
Freight AU$ 260.00

Total AU$820.00

I'm not suggesting i'm being ripped off by Tom Wood, the stock shaft is about AU$ 750.00 and i'm sure his is better, but it is had to see so much value in a round pipe that spins around and around.

It is approx. 1/3 of the cost to rebuild my engine including the cleaning and machining. It is more than I paid to have my auto disassembled, inspected and de-glazed.
