3yr old rear
Maybe 15k miles.
im in New England - often on coast in Summer. Rebuilding necessary, despite oil change greasing. Center ball gets greased but not well enough without benching it..

front was done in the same fashion.
I just painted front again this year.

It’s 160 + the ride one way for TW to fully service. That’s an expensive package for both front & rear inside a few years. I lm going to try to seal and better coat them. Oddly enough the stock rover shafts I have on the shelf are not this rough or in need of u joints in the same time span with minimal maintenance - and these presumably have 200+ miles on them.

 

I greased my drive shafts religiously. My Tom Wooods center-ball dis-integrated after just couple of years of use. Good thing I caught it in time before it completely fell apart.

 

I'll be honest I'm completely un-excited about the TW driveshafts.

2 years ago, I got the good HD one for my 00 Disco, and it arrived unbalanced. Immediately a terrible vibration around 40-45 mph on my STOCK unlifted (at the time) D2. To their credit -- Although they offered to help me rebalance it, or return it to them and swap it out, I took it to a local driveshaft shop and they balanced it. And they told me it was probably not a balance issue and was something to do with me having a lifted truck and the angle of the whatever whatever as a result. Anyway, I explained that my truck was not lifted and was stock. To rebalance cost me 120. Which sucks when you already pay 400 or whatever it was for the TW driveshaft.

The driveshaft shop said it was great quality but it just was not balanced properly.
