MJRemi Posted January 26, 2011 Share Posted January 26, 2011 I want to upgrade from my 3.07 D35 2wd. I was wondering if this 8.8 would require a laundry list of mods to make it worth it. http://sandiego.craigslist.org/nsd/pts/2169940699.html I can also get a cheap D35 from a 86 MJ 2wd 2.5 or a D35 from a 92 XJ 4wd auto 4.0 . Thoughts & comments?? Link to comment Share on other sites More sharing options...
shelbyluvv Posted January 26, 2011 Share Posted January 26, 2011 Other than it missing about $200 of brake hardware, nothing. Link to comment Share on other sites More sharing options...
Geonovast Posted January 26, 2011 Share Posted January 26, 2011 8.8s are narrower too, aren't they? Link to comment Share on other sites More sharing options...
91coMANche Posted January 26, 2011 Share Posted January 26, 2011 8.8s are narrower too, aren't they? Not by much (around .25 on each side). Link to comment Share on other sites More sharing options...
mvusse Posted January 26, 2011 Share Posted January 26, 2011 Perches would need to be cut off and new ones welded on in the right place, and an adapter of some sort to mate your drive shaft to the 8.8 mounting flange. May possibly need to shorten your drive shaft as well. Even so, I would not bother putting another 35 in, unless it is from an MJ (only straight bolt-in) and was given to me for free with nothing wrong with it. I would look for a D44 from an MJ first, which would be a straight bolt-in, but may still need to shorten the drive shaft, or a D44 from a 90 or older XJ Cherokee or Chrysler 8.25 from a 97 or newer one. Both of those need the perches moved and possibly the drive shaft shortened, but they are the correct width and have the correct yoke for your drive shaft.

richasco Posted January 26, 2011 Share Posted January 26, 2011 The adapter is found on the driveshaft from any Ford that had the 8.8. It even uses the same u-joint as jeep driveshafts. Don't be too quick to buy an axle that is missing brake parts, unless it has really low mileage and a limited slip. Edit: it's got the limited slip but had drum brakes, you should be able to find one that has disks. Link to comment Share on other sites More sharing options...
MJRemi Posted January 26, 2011 Author Share Posted January 26, 2011 I've decided to pass on the above 8.8. I can get a D44 (XJ) with 3.54 ratio for about $300. It is complete except for the brake lines. I can also get the MJ D35 with 3.55 from a wrecked 86 for less than $150. If I get the 44, what type of shop would I contact to shorten my driveshaft and/or weld perches in the proper positions? Link to comment Share on other sites More sharing options...
mvusse Posted January 26, 2011 Share Posted January 26, 2011 You can remove the old perches yourself with an angle grinder. Any fabrication or exhaust shop should be able to weld new perches on. Shortening a driveshaft has to be done by a drive train shop, as they have the equipment to rebalance it after the work is done. Link to comment Share on other sites More sharing options...
