Q: What other parts do i need to install this. eg; bearings Answer this question

A: GC- Thank you for your question. Any time you install a new carrier it is advisable to replace the ring and pinion along with the shims and bearings. It is almost imposible to match the wear pattern in a used set of gears on a new set up and this will result in gear whine and premature wear. The instalation kits you will need can be found here
