I have a 2000 XJ that I want to swap out my low pinion Dana 30 front axle for a high pinion version. If I take one from a 98 or 99 Cherokee will it be a straight swap of just the front axles or will i need the driveshaft from the high pinion axle as well? Anything I need to know before doing this? I a noob at this so any advise will be helpful =)

 

Bump... im sure someone has done this before. Any info would be appriciated

 

Straight swap.

 

Thanks man... stock gears for mine is 3.55 right? Sorry I'm still learning

 

Assuming you have 4.0L and an AW4 tranny, then yes the gear ratio is 3.55.

 

should be a tag on the diff

 

Anyone have a picture showing both LP D30 and HP D30? How does one tell the difference?

Unless your running a big lift or larger than 33s i wouldnt waste my time swaping them out to be honest.

 

HP Dana 30 is stronger since it uses reverse cut R&P.

It's a very smart upgrade.

 

Yes but the majority who worry about this dont even need that lil extra strength. A waste in my eyes. Hell there are locals here running 37s on LPs in the tj community without issues just saying.

 

If your gona swap then go stronger or find a d 30 with a locker. no sense in putting a stock diff back in if you can put one in stronger with little work. I would go d 44 and you can find those ready to go in your jeep for a few hundred. At least have the new diff trussed or built up so its stronger than stock. Your doing a lot of work for not much better and really if you need that extra room and extra strength then you should do it right and a stock hp d 30 is a waist of time. Unless you are in need of a new diff because your current one is needing to be rebuilt, dont do the swap.

 

Thanks! I have a high pinion on my '88 XJ.. thought my year only had low pinion..

*Edit--- nevermind, I was getting my facts reversed...
