Re: dana 30 front end
The Ford 9" has very strong pinion and axle shafts,beefy axle tubes and strong R&P, but it does drop the rear drive shaft to low unless its major modified like Curry does with the pinion on top. Also the 9" you were looking at with 28 spline is considered the weaker axle as compared to most which are manufatured as 31 spline. Another axle that is often overlooked is the Ford 8.8 from an Explorer it is 60 1/2", has the same axle,pinion and tube diameters as the 9" only a slightly smaller ring gear diameter(thickness of the ring gear is almost identical), it has a super strong pinion yoke set up, and on 95s and newer has Disc Brakes. Its a very easy swap on a YJ, I wouldnt think it would be much different on a CJ. I lost 1" of clearance as compared to the Dana 35. check out the attachment of the view of the Yoke, the pinion angle is set high because I broke a leaf Fri night, the axle wrapped so far that the yokes bound up and disinigrated a new spicer U joint, But no damage to the yoke. I would say average cost for a set up with discs is just over $500, They typically have 3.73 gears and a Trac Lock.
If at first you dont succeed, your replacement will try and try again.
