Thread: Another adapter shaft bites the dust

Daz,I don't think Ashcrofts is fixing the whole situation,looking at photo's of failed shafts,all of them have stripped the last 1'' or so of splines,meaning that the shafts have walked out of the cup,lubing is only half the problem. Pat

Pat, I completely agree with 100% with regards to the Ashcroft solution isnt addressing all the issues.
*So far I have not had any of the Ashcroft kits I've installed fail (yes I know there have been failures).
*Its still a better solution to the standard setup.
*The adapter shaft can move back into the transfer case aprox 8mm.
*The adapter shaft really needs to be supported with bearings or a retaining bolt down its length to prevent movement (like the adapter shaft on Disco 2 setup).

*Just about every Jeep on the road has the same setup using an adapter shaft and housing to mate whatever auto/manual box they were using at the time to their transfer case. EVERY single one is assembled DRY no lube on splines. BUT the adapter shaft has support bearings to prevent any side movement. I have never replaced a damaged/worn adapter shaft on a Jeep.

*Simply put.... the cause is Jaguar Land Rover and yet another example of their under done engineering.
