Disc Brake Conversion for Dana 70
Q I'm looking to make my Dana 70 HD dually into a full-floater disc-brake rearend. I know that the RVs and U-Hauls have them, but don't know how to acquire the parts to do it or where to buy them.
A Not a problem. Several companies offer a disc-brake conversion kit for the 70. One of the nicer conversions uses a special formed adapter plate of 3/8-inch steel, and front rotors and calipers from a Chevy 3/4-ton pick up. It's advertised as for a GM 14-bolt application, but I understand that it will also fit the Dana 70 HD. Take a look at www.ruffstuffspecialties.com
Rx for Wrangler Rust
Q I have an '89 Jeep Wrangler with a rust problem. Being that I live in Michigan, I am sure that you know what I'm talking about. The body rust I can live with, but the frame has some problems that I'm sure need attention. At the rear, where the end of the spring mounts, the frame is pretty much rusted out. Other than buying a new frame, is there any way I can have a shop weld in new patch plates, or something else I can do to fix this potentially dangerous situation?

A It's just not in Michigan that rust in this area occurs. It's a pretty common problem with all YJs that are used in snowy, muddy areas. It seems that this is a great place for junk to collect and hold moisture. Fortunately, there is a company, Auto Rust Technicians (800/407-7024, www.autorust.com), that makes repair kits for not only this problem but others. You should also look at the front shackle mounts, as they're also subject to rust out. Auto Rust Technicians also make repair kits for 1967-86 Jeep CJ-5s and CJ-7s that experience that same problem, as well as for the Wagoneer's rear frame member, where the skidplate mounts.
