Trying to figure out what to use for spring pack center pin.
A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.
Easiest; Go to NAPA. They usually have them in stock. You just need to know the diamiter 5/16 or 3/8. They are all cut to length. Buy a coulpe of extras, they come in handy. Also if you find yourself on the trail needing one, a 1/4" drive extesion about 2" long works great. Voice of experience, I sheered one off on the trail once and this kept me wheelin' for the weekend. Now I just carry a couple extras.
Order 3/8 pins and get a good drill bit. Drill the springs out to 3/8 and the pins will not break as they do using the 5/16 center pins I've done this on all my jeeps. If you have a lift and are using wedges for your pinion angle the small pins will break quite often. After I drilled my first set I never had one break again. But make sure you buy some quality center bolts not the ones the chain stores sell.
I get spring center pins, bolts, nuts, washers, etc. from a local spring place.
