im not sure about this,but i thought 91 front axles had the vacuum thing,i dont have one,does this mean it was swapped out? or was it a package from the dealership? the PO had this jeep from 91-10,so i reckon she could have swapped it out,but im not sure

 

i went and looked at my 90 and i dont have it, and i know i ahve the origional. so you should be fine.

 

If your 91 has the NP242 Fulltime 4WD TC it won't have the vacuum disco. If your 91 has the NP231 Partime 4WD TC it will have the vacuum disco....unless like you say the PO could have trashed the axle and somebody swapped in a non disco or newer axle. In 92 ALL XJs went to the non disco D30 whether they were fulltime or partime 4WD.

 

im glad i dont have one,i dont have the spot for it,i rather have not have one

 

i got the np242 so i reckon thats y i dont have one

 

YEPPER DUDE!!!! But, all 91 XJs ROCK!!!!!!!!

 

hell yea,best year ever! for xj's

 

i dont know i think you all are a year late...

 

Nope, 91 is the shiz. Rock on dudes.

 

well since i dont have the vacuum thing.....then what do i have?

 

the axle with out one?

 

well yea...of course,but what makes one better than the other,is what i shoulda asked

 

the one you have turns every thing all the time mine i can turn my drive shaft freely when not in 4x4 yous is locked

 

oh ok,thanx,i wasnt sure...
