Thread: How important are U-Joints

One of the things I need to do is grease my U joints. One of the previous owners replace the standard U joints with the grease-able ones. How often should these be done?

Thanks

Truth is, it's had a number of mods underneath, so I guess it got swapped then. I didn't know they ever had 'em.

Don't know if there's a 'recommended' interval, so I would suggest every oil change, or more frequently if you do a lot of dusty miles, or water crossings, that sort of thing. Most of the failed ones I've seen have been rusty.
It only takes five minutes if you have a good grease gun.

Aren't the double Cardans problematic?

I've been told they are if the car is lifted. It increases the angle that the joint has to work through, and unis aren't good at that, even when there's two at the same end, or so I've been told. That said, mine's been lifted a while with no probs, but... They say if it fails it can do catastrophic damage to the TC.
I've been wondering if there was some sort of conversion, to something like a CV joint. Guess I'll talk to a driveshaft bloke and see.

Yeah believe they are 16s. Going to see the car tomorrow. Any suggestions for a good off-road tyre without going too crazy on the price ? Nothing too extreme needed, I plan to turn it into a family tourer rather than some rock hopper.

Re the DC, I hadn't thought about that when I said 250K km. My P38A didn't have one.

As mentioned, more so when lifted , but not really a problem with quality greasable uni's

Already answered but just to add that when you grease them just pump the gun until you feel the trigger go hard , if you keep pumping so the grease breaches the seals then if you have a warm / hot uni after say a long run then go through water this can and does draw water / dirt back into the needle rollers shortening their life

Some have done this mod , the 200tdi disco's had u/j as well , personally never had issue with rotoflex.
Also re double Cardin , when they let go ,their likely to destroy gearbox and/ or tunnel

All terrain or mud ?
If your not going to lift it then 245/75/16 are a good size , will make speedo read around 5% slow
Lifted by 2 inch 265/75/16 looks a bit better ( more proportioned)
but speedo now around 9-10% out and a noticeable reduction in torque, but still acceptable, especially with remap

I'm going to get a pair of Wind Force All Terrains, The specifications test results and data look good and I get these at wholesale, so at $65 per tyre it's a good price to try them out.

$65???? About $200 less than my Maxis. Let us know how they go!
