I'm about to be going from a 3inch to a 4.5inch lift on my 2000xj. I was wondering if I will run into any problems having a low pinion dana 30

I have never heard of anyone running into drive line issues with the LP-D30. I would say if you do, a t-case drop kit would be the ticket. As far as I know no one makes or offers an SYE kit for the front d-shaft so I guess it's not normally an issue. Good Luck!!

mr mcfly

me either....im at like 7" and i have a lp d30 although i cant say i have had it for a long time. theres already a double cardon joint on the front shaft and a slip yoke near the axle as you probably know

I have 4.5 with LP 30, and I'm good

LP30 and a 4 1/2 lift on my 2001. No issues.

you have never heard of one because the slip yolk is on the driveshaft not the tcase. Should be fine its only a couple inches lower than a HP.

mr mcfly

^^ yea.....if you compare the lp and the hp where the end of the pinion attaches to the shaft is probably only 2-3 inches difference. seems the hp is desired because the bulge of the gear is on the top rather than the bottom giving you more ground clearance at that point.....and the way the teeth are contacted is technically stronger with the hp design.

THe main issue is driveshaft bind, as wellas caster angles. Caster angles wil contibute to DW if not addressed, and has led lots of ppl to spend money and not fix the issue until caster angle is corrected.


Also the pinion being so low. it can create d/s bind once flexed, and in some cases will cause yoke failure, as well as u-joint failure.

So just a alignment right?

mr mcfly

caster angle is only going to be compensated for correctly if there are adjustable arms to tilt the axle back after a lift....as far as drive shaft bind i am curious? im not saying your wrong by any means, but my logic would be the low pinion would actually create a straighter overall drive shaft angle than the high pinion one would. say the high pinion angle would be parallel to the ground (never actually measured this, just saying for the sake of the convo). wouldnt the low pinion angle be tilted slightly upward compared to the high?. because it is contacting the ring gear at the bottom rather than the top? please correct me if i am wrong

both exit the diff at the same angle. one is just lower then the other. the LP causes a more steep angle on the joints, mainly causing binding on the diff side joint and the Double cardon joint can handle it. Ihad a 4.5" lift with a LP30, was fine, no issues. I know someone with w 6.5" kit, no problems from him.

I now have 5.5" lift, and a D44. no issues even at full droop. I wouldn't worry about it, wheel it!

mr mcfly

oh ok....i figured they were at different angles. makes sense now, thanks.

srhcherokee24

They are fixed lowers. I went with them till my buddy gets everything figured out for the long arms he is starting to make

srhcherokee24

What did u get the dana 44 out of

a wagoneer. Its a LP as well.
