so i have a 2000 xj with LP Dana 30.it has all new u joints and unit bearings and a spartan.one reason i want to swap for a high pinion is my pinion bearing is about shot.My father in law has a 95 parts jeep with a hp.can i gut my axle ( unit bearing axles with the bigger u joints and my locker and put new seals in the donnor ?will it all fit?i also have the stupid pre cats ,will this be a problem? thanks for any info. oh what about drive shaft length and any thing else im overlooking ?

 

Unit bearings won't work. Everything else should swap over though. Some run into issues with the pre cats, if you you're lifted it should be better though.

 

is all Dana 30s 29 or 27 spline ?i get it confusrd with the 8.25

 

i have 4 1/2 lift

i

 

27 spline D30.

 

Shoul fit with lift you have might grab the drive shaft also from donor.

 

Driveshaft lengths

 

thanks guys im going to start gathering parts.are all the listed driveshaft's ujoints interchangeable? mine are new and i would like to swap them in the next shaft i get.my shafts slip joint has play in it but my ujoints are new spicer ones

 

Yes same u joint on the shafts

 

the shaft gone already but the pinion is tight.

does anyone know how to check for bent tubes?the donor jeep wad a trail rig that was rolled on the trail but not bad.just hate to do all the swapping and find out its bent
