I got impatient tonight. I wondered over to Advanced Auto in search of U-bolts for the rear u-joints to replace those weak *** straps. I found some 3 dollar u-bolts in the HELP section. Not sure if they are the strongest, but we shall see. You need to be 21 to do this upgrade (at least my version)
*Buy a 6 pack, perferably Yuengling for you Pennsylvanians
*Open up beer one, finish beer one. Open up beer two, and get under Jeep.
*Take out the 4 bolts on the rear yoke. Take off the straps and let the driveshaft hang out of your way. Sip beer
*You'll need a 5/16 titanium drill bit. (8 bucks) Drill the threads out and make the hole a bit larger in the rear yoke. sip beer, open up another
*Test fit and make sure the u-bolts fit the hole. you guessed it, sip
*Put the shaft back into place, and secure the universals with the bolts.
*Put the supplied lock washers and nuts on. finish number two, and you 'should' still be good for a test drive.
Good Luck and drive on
