91coMANche Posted March 7, 2011 Share Posted March 7, 2011 So I ordered some U-Bolts to arrive tomorrow. They only have 2 7/8" U-bolts. Will that work with an MJ 44 or do I need to get some made in 2.75" (possible but a far drive compared to what the parts store is getting me by tomorrow). Just want to know before I take apart the manche tonight. Link to comment Share on other sites More sharing options...
Dirteatr717 Posted March 7, 2011 Share Posted March 7, 2011 X2 I'm doing my SOA soon and kinda sorta forgot I need new u-bolts :peek: :fool: Link to comment Share on other sites More sharing options...
91coMANche Posted March 7, 2011 Author Share Posted March 7, 2011 Well Dorman makes ubolts in the size I posted BUT not in 2.75". Let see if anyone can confirm fitment. Link to comment Share on other sites More sharing options...
johnnyc Posted March 8, 2011 Share Posted March 8, 2011 They'll work fine. The difference between the two is only 1/8". Link to comment Share on other sites More sharing options...
Eagle Posted March 8, 2011 Share Posted March 8, 2011 So I ordered some U-Bolts to arrive tomorrow. They only have 2 7/8" U-bolts.

Just want to know before I take apart the manche tonight. What diameter u-bolts are you getting? The stuff I've seen in most parts houses is typically 3/8" or 7/16". The OEM u-bolts for the MJ are 14mm -- the nearest SAE equivalent is 9/16", although I think a GOOD quality 1/2" is fine for most ordinary purposes, and better than a 20+ year old, rusted-out 14mm. But I wouldn't go smaller than 1/2" Link to comment Share on other sites More sharing options...
91coMANche Posted March 8, 2011 Author Share Posted March 8, 2011 These are 1/2" thick, 2 7/8" axle opening, 8 inches long. Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 8, 2011 Share Posted March 8, 2011 These are 1/2" thick, 2 7/8" axle opening, 8 inches long. They will work fine, best if they are grade 8, bit long though. Use grade 8 HI nuts with them (more thread engagement) w. a couple of flat washers , torque them up, then add a lock nut. After a couple of hundred miles, re-torque. That's where I am now on my D44 install. :cheers: Link to comment Share on other sites More sharing options...
91coMANche Posted March 8, 2011 Author Share Posted March 8, 2011 Thanks Don. I didn't buy the Dorman ones because I found out they are Chinese. So I went to the spring shop near the driveshaft shop that shorted my shaft and had some 2.75X8X9/16" grade 8 bolts bent along with grade 8 hi-nuts and grade 8 thick washers. $60 for the set but well worth it to first off support :USAflag: and consequently get a quality product.

Sounds good. Let us know how they work. :thumbsup: Link to comment Share on other sites More sharing options...
91coMANche Posted March 8, 2011 Author Share Posted March 8, 2011 Just got the 35 out. The new U-bolts seem to be exactly the same size as the ones I pulled off the 35. 2.75" tubes on the 44 and maybe the 91 Dana 35? I know later Dana 35's had 44 sized tubes. Perhaps the C-clip 35 uses the same tube? Link to comment Share on other sites More sharing options...
johnnyc Posted March 8, 2011 Share Posted March 8, 2011 Again, the difference between the two is minimal - 0.13", just over 1/8". So the factory likely used the same u-bolts for the D35 and the D44. Link to comment Share on other sites More sharing options...
91coMANche Posted March 9, 2011 Author Share Posted March 9, 2011 Factory could have worked with the Dana 44. Once under there my new grade 8 u-bolts worked perfectly. Axles in, driveshafts in, and weight sensing valve is ready to hooked up but not before i pull the cover to reseal and refill some 80W-90. If only I had a posi!
