    ? about rear DS length for 3 1/2" spring lifted 93 yj

    My buddy has a 93 YJ with the 5 spd transm and thinks his stock rear DS is now too short after a 3 1/2" spring lift, no body lift. Any ideas on what he needs and anyone have an extra one that may work for him? TIA

    Your buddy should join the forum.

    My first question is...does he have an SYE?

    My second question is...what has led him to the conclusion that his existing shaft is too short?

    My first suggestion would be for him to measure yoke to yoke (or slip yoke to yoke if no SYE) and then take the measurements along with his existing DS into TAD Shafts at I-17 and Deer Valley and have them make him a new one.

    My second suggestion, if no SYE, would be to install one, and then have TAD make him a CV shaft.

    I think I have a couple of YJ front shafts and some spare rear shaft parts, but I do not have a complete spare rear shaft at this time.

    I also have a 93 YJ with 5 speed. It's been a long time since my YJ had only 3 1/2" of lift but, IIRC, 2 1/2" is about the limit with a stock rear DS before getting vibrations. And with the slip in the tcase tail cone, if you pull the shaft out of the tcase, you can lose fluid. Sounds like it's time for a SYE and CV shaft. I second TAD.

    Apparently a rear DS off a 4 cyl yj will work as it is 14 1/2" instead of 13 1/2" like he has now. Anybody have one laying around?
