Wrighty8766 Posted March 11, 2015 Share Posted March 11, 2015 Where have you filled the oil upto there bud? Should be just above the cross pins otherwise it will cause extra strain on the diff and can cause...ermm...pins to snap etc Quote Link to comment Share on other sites More sharing options...

I'm not sure sorry bud, I would imagine the hot bodies lightning ones would fit, and probably be tougher....in 12 months I haven't broken a stock one yet so I haven't looked into it!...I musnt be driving it right Quote Link to comment Share on other sites More sharing options...

It's just that when something fails unexpectedly in the same place more than once, then there maybe an underlying cause. Look for things like a raised edge on the outdrive cup pin hole, worn bearing or wear on the gear side diff housing. Anything really. Make sure it's the right pin though, wrong one wouldn't last long. I'd take it as an opportunity to really bullet proof the diff with a vorza cup, hardened gears etc, get rid of the thin 10mm bearing. I'll leave the part numbers in case you need them.

You'll just use the original steering post, it the bit with a hex head on one end and the thread with spring & collar on the other, 4mm thread showing with compressed spring. The other post looks different, it's just shorter is all, bearing is further up. Edited March 12, 2015 by fornowagain Quote Link to comment Share on other sites More sharing options...
