I have a 1991 XJ. Im pretty sure its a later model because it does not seem to have the vacuum disconnect. 89-95 with ABS have 5-297x U joints. 95+ have 5-297x U joints, and others have 5-260x U joints. I just want to know if I have ABS so I can determine my U joint size.

Thank you in advance

 

On a 91 with ABS there will not be a vacuum assist brake booster, it will have the Bendix 9 ABS system with an accumulator and motor. A quick way to tell if you have ABS would be to look for the ABS light to come on for a bulb check when you first turn the key on.

 

on my 99, it would be where the red arrow points to.

 

Thank you. I should have thought of that lol

 

One mine, which is a 90 with abs, the control module thingy is under the rear bench seat on the drivers side.

 

Slam the brakes.

 

Yea under my rear bench is empty.

 

Then look where bbasso said on the later models I believe it is right next to the brake booster. Or you could get a build sheet and that'll tell you everything!
