How necessary is it to install master overhaul kits when doing the ring and pinion swaps? It cuts the cost of doing this project in half and allows me to maybe get new 32s before winter... |

My kit for the front wasn't awful expensive - around $125 |

So...how long can I run 32s until I need to regear? I'm sure I'll notice a huge power loss and mpg loss but with winter coming I'd like to put some fresh tires under her. I'm currently at 6/32s with the General Grabbers which would get me through winter, but not as nicely as I'd like. |

I'm currently at 6/32s with the General Grabbers which would get me through winter, but not as nicely as I'd like. How long ?? Hard to say, with mine I couldn't use overdrive at all at normal highway speeds even on flat roads with no hills. If I tried it just shifted back and forth, engine would run hotter, transmission slipped if I continued to do it, engine would just lug down to where it wasn't running right. Mileage dropped 6 or more MPGs . So sure you can run it, but with increased wear to both engine and transmission. Plus the extra cost of the gas you'll be using. I'm glad I only had to run a couple of weeks before my rear gears could be done ( already had a front 4.10 diff) With the way KKs seem to suck gas anyways I think I'd find someway to do the gears ASAP |

Do the rear and remove the front driveshaft until you do the front diff |

Why 05+? I thought it all just had to be for the 29 spline 8.25. I'm a newbie with regearing so I could be entirely wrong. |

From what I'm seeing they changed the axle in some way for '05 and newer. Not sure why...but I think the splines are different. If I remember right, the older ones were a 27 spline. So if that's the case then Chrysler went to a 29 spline...for some reason. |

All KJs were 29 spline, even last model year of the XJs |

Yep 01/02+ should be 29 spline. Are there any specific brands to look at? I've heard a lot of brands sell the same product and you just pay for the name. |

The way I see it is it's a hunk of metal spinning via a different hunk of metal...so long as the teeth rotate it should be good. I have heard of rings breaking or tooth fractures in hard wheeling though. |

http://eastcoastgearsupply.com/i-139755 ... -4-56.html http://eastcoastgearsupply.com/i-117855 ... -4-56.html Pretty sure they're 29 spline. They claim they fit 01+ Libertys. I'm assuming they group the 01 XJs in that. |

Nitro 4.56: http://www.justdifferentials.com/C8-25-456-NG-p/c8.25-456-ng.htm Motive 4.56: http://www.summitracing.com/parts/mgr-c8-25-456/overview/ Both of which state that these are a 27 spline. Unless each company makes a 27 and a 29 spline... |
