So I went ahead and bought some 4.56 gears for my jeep and my question is how hard are they to install or should I even attempt it myself at all? I do have some mechanical skills but Im far from a pro...
I've never done it, but you'll get all sorts of comments. To some guys, it's a piece of cake. To others, they say that after trying this, they now know why shops charge as much as they do, for this type of work.
As I understand it, you need GREAT patience.
Me...I'd have a shop do it, or the help of someone who really knows this stuff to help me, which is basically, me watching him do the job!
If you do tackle it yourself, make sure you have everything you need before you start. (ie. extra shims of varying thickness, a spare crush sleeve etc.) One last thing, what gears are currently in it and have you made sure you have the proper carriers for the new gear set?
'84 CJ-7: Yota axles (spartan locked front, e-locked rear) 4" BDS, 1" Daystar & 3/8" shackle lifts, 35" X-Terrains on steelies, YJ Tub & family roll bar, heater blower upgrade, 4.2L w/MC2100 & Team Rush, Warn 8274. Rebuilt 4.2/4.0 hybrid, AX15 and twin sticks/clocking ring waiting to go in.
The advertised position for a topless, dirty jeep girl has been filled......by my wife. Thanks to all that applied.
<------------and yes, that is her. :-D
you will need a bearing puller and a magnetic base dial indicator among other specialty tools. I learned to do it myself by reading articles online. It is not difficult but it is tedious. My mechanic quoted me $600 per axle to setup gears and that is when I learned how to do it myself.
I had mine done, a friend of mine that owns a shop that specializes in jeeps did both my front and rear gears, drilled and tapped the hole for an air line in the top of the diff, and installed my ARB lockers for $1000. I did the wiring and installed the compressor. I am satisfied because at least I know everything is right, puts my mind at ease.
