Ok so I have a couple questions about swapping into 4.10's (decided that was the best route for me, so I dont lose on top end speed I think?):

1) How difficult is it? I mean I have a basic set of hand tools (sockets/breakerbars/wrenches, the basic stuff) but how hard is it to change?

2) Limited Slip? Would that make the job more difficult?

3) Would it change my speedometer? Would it be off by just changing gears?

4) Anyone have a write up on it? It would make changing it much easier =) Or am I needing high dollar tools and best route would be take it to a shop? How much do they normally charge if i have the parts?

Sorry it's lengthy but I'm curious

 

as far as i know the ring and pinnion install is actually wicked tricky... you gotta adjust for backlash, ring tooh pinion tooth matting surfaces... a ton of garbage you gotta make sure is perfect... i dont know any forum that has a write up on the 9 1/4

im sure they sell DIY books and sorts that would prolyl help..

 

From whats I've heard its hard like shott said [&:] Adjusting all that crap with shims and goodies. If I ever change gears I'll probably let somebody else do it

 

Would it affect the speedometer if i changed gears? I know some vehicles it will some wont.

 

Yes your speedo will be off. Being that you have OBD2 you should be able to get some sort of programmer and adjust for it or I think you can buy different speedo gears to match it. Am I right gang??
