Rule to the masses -- big sticky grabbers will break stock parts sooner of later ...

Re: U joints recommendations
 

keep a check on your axles also.

Re: U joints recommendations
 

Good advice Sam.

I think I will just take it easy (i.e. street tires) on this one once it is roadworthy. Will then turn our attention to finishing up some landscape projects and building the work shop.

When I get back to it, I guess if I am going to drive it REALLY HARD with sticky tires, I would want to eliminate the c clips and go with some good aftermarket axles. Could get ugly on the quarters if ones twists off.

The solution for the Muncie is to install steel bushings in the case. Helps distribute the load in the aluminum and stop the gears spreading.

An iron midplate and Super Case will help, but you will still grenade a Muncie on slicks if you drive it like you hate it. I have a lot of hard miles on my Auto Gear M22 but always on street tires. Also use exclusively Spicer solid u-joints.

I have a done-up Auto-gear M22 in my 66 straight axle Nova that I run Hoosier slicks on and I run it hard. In three years it has yet (Emphasize Yet) to break. I have to say after grenading more Muncies than I can count, I'm impressed with the Auto-gear stuff. The roller-bearing side cover makes them shift better than than you can imagine, and if it blew tomorrow I've more than got my moneys worth out of it...

Re: U joints recommendations
 

Yeah, Auto Gear is good stuff for sure. Just wish the case looked a little more like OEM.

Re: U joints recommendations
 

Another problem with Muncie's is that the cluster shaft is not centered in the main case from the factory.

I'm running a stock Muncie with aftermarket M22W gears in my car launching at 4000rpms with M/T ET Streets. No issues so far, knock on wood.
