Thread: D2 Front Tailshaft

In Melbourne
I have used a company called Ken Hastings balancing Services, from memory in Preston, they basiclly pull it apart, fit new greasable uni's & rebalance the "WHOLE" shaft & even paint it beautiful black .
All for around $325.00, i did mine last year after the Simpson..Dust, Dirt & road grime are a major contribution to failure as u cant regrease them. The A/C drains also dont help but this is only when the vehicle is sitting still.

Very expensive that lift job.
So if I went for the greasable ends on both shafts re routed the drain and kept the standard suspension height but upgraded the height of the tyres (to lift it a bit). In theory the car should last me with no shaft worries?
How often is regularly greasing as refured to by BigJon, surely not every time I hit the dirt?

Dobbo,
The rear shaft is already greasable, if u dont have a nipple at the front end of the rear shaft there is a hole there(hex nut) to be removed so u can fit one. The rear end of it just bolts to the flex rubber donut.
I havent had any problems with my rear prop shaft in 230,000kms.
Just proper maintenance, i normally do mine every 5,000k or if i have had a rough & dirty trip.
Cheers.

RE which is weaker of the 2 types of joints...

Ive been doing lacky services on trucks for ages never seen a prop shaft sans greasable joints and Im talking trucks with engines pushing 300-700hp and Minimum peak torques of 1200nm. ditto for mining equipment But a word of warning...

greasing them untill the grease squishes out of the seals is bad Karma, put 1 shot of grease from a correctly bled grease gun once a month or so for normal use and thats about it.

too much grease opens the seals, which then deform and let bad juju in.. when i had em I use to replace non greasers every 12 months and greasers every 24, takes about 30 mins per joint.

When they are correctly filled you will see a very fine line of grease dots along the guts of your vehicle perpendicular to your prop shaft inline with the uj.. If you see large gobs theyve been over filled, the seals have failed or you need to clean under the car more often.

Given the lengths of the shafts and the rpms they do knowing I have good joints gives me a warm fuzzy feeling every time I have to drop to fourth gear and stay on the loud pedal when going up hills.

Dave,
I agree wholeheartedly, i never over exert the grease gun, just a dab to just see the rubber move & thats it, never to see the grease escape because what u have already said.

I think more is to do with how and where I use it than the lift itself. I guess it'll be interesting to see if I break another one this Xmas, which is when its due. I haven't done much tough 4WDing this year which is unusual. If it breaks then I'll assume its the lift, if it doesn't then I'll assume its the driver.
