The front slip joint should see virtually no wear, as both ends of it are attached to parts that barely move during operation.
The rear will definitely see more movement, but the Toyota drivelines I’ve worked with had no noticeable slop.
It really does seem Toyota over-engineered these things and as long as maintenance is done correctly they can see a very long service life.
That said, my front driveshaft didn’t seem to have been greased once in the vehicle’s life before I got it.. approx 100k miles. I started greasing it and monitored. After another 100k it did start vibrating, which is what led to the joint replacement I did a few months ago. The rear wasn’t indicating any problems but I did them while I was in there.. pretty sure you’d understand that decision.
Also you may know this already but in case you don’t, you can remove the front driveshaft and lock the CDL to drive the vehicle while you’re working on replacing those joints. This will disable the VSC and make it pretty squirrelly in scenarios with reduced traction, but buys time to source shim clips or whatever you need. I have even reversed that tactic and driven mine in FWD before for a day..
Thanks
Yeah, i will remove them both and inspect before making any decisions on how to proceed.
I've replaced a fair amount of ujoints over the years, and i dont remember if it was my 80 or my 100, but one of them had the splines so worn it was unrepairable. Guessing was loaded with grease, driven in dusty conditions, and the sand just ate away at the splines.
I am still chasing a VERY slight thud/clunk that is now narrowed down to the shaft ujoints, or the backlash of the 3rd member. Thats all that hasnt been replaced yet. LOL
Good call on the CDL after removing front shaft. Honestly, didnt know about that. Oh maybe i did and forgot. Ha
Never recall shims or such things when replacing ujoints, going to look more into this.
Thanks
