johnny quest Posted October 10, 2012 Share Posted October 10, 2012 Do I need to do an SYE on my 231 with a shortbed that's got a SOA in the rear?? Link to comment Share on other sites More sharing options...
johnny quest Posted October 10, 2012 Author Share Posted October 10, 2012 Let me explain better: does my truck need it, or am I wasting time/money on something that isn't necessary. Link to comment Share on other sites More sharing options...
NotMatt Posted October 10, 2012 Share Posted October 10, 2012 You do not. My brother's short bed truck was SOA in the rear and never had a single problem with driveline angles with AW4/231 combo. Also, you should not have any driveline bind... but if you DO, you can clearance the driveline yoke a slight amount with a die grinder and get away with it, at least temporarily so the truck is driveable. Another option, if you need more yoke length and a little more room for the u-joint to move around, is a slip yoke from a stock YJ driveline. It's about an inch longer in length, and the ears are larger to allow for more movement. Swap that onto your stock driveline after the SOA and you'll be golden.

Zebvance Posted October 10, 2012 Share Posted October 10, 2012 Depends on how much lift u have. I just ordered one for my swb mj. I have soa with a total of 7.5-8.0inches of lift in the back. I have very slight vibrations around 25 mph then they go away. Link to comment Share on other sites More sharing options...
Zebvance Posted October 10, 2012 Share Posted October 10, 2012 So anything under 7.5 I would say no you do not need one. But you will need a longer driveshaft. I have one for about 4.5-5.5 inches of lift I will be selling as soon as my sye and Tom woods drive shaft come in. Link to comment Share on other sites More sharing options...
johnny quest Posted October 10, 2012 Author Share Posted October 10, 2012 SOA 14 bolt on stock springs gave me about 4.5" or so. So I should be fine?? Link to comment Share on other sites More sharing options...
Zebvance Posted October 10, 2012 Share Posted October 10, 2012 I would say you are but prob still need a longer drive shaft. Post a picture of where your driveshaft attaches to the tail housing of your transfer case Link to comment Share on other sites More sharing options...
NotMatt Posted October 10, 2012 Share Posted October 10, 2012 SOA 14 bolt on stock springs gave me about 4.5" or so. So I should be fine?? Hard to say, but the 14 bolt is longer in the snout than any of the options of what you might have pulled out, so you should be fine. Only way to know is to bolt it up and have a look see. Post a pic after you get it bolted up like Zebvance said, or simply compare the area that's polished down by the seal on the yoke to where it fits now in the slip.
