Does any one know of a good on line source of dana parts like ring and pinion sets and a spreader. I'm going to change ratio from 410 to 355.

 

How hard is that to do? I've saw a lot on e-bay. These 4.10's let the engine rev higher than i'd like.

 

Randy's Ring and Pinion is a good place. They were the only ones to have the R&P for my Dana 80. I just regeared a Dana 80. The first rear end I have ever done. I think it was a sort of hard job. A lot of thought and research went into it. I needed a few tools that I didn't have.

On the hardness scale- If you can rebuild a manual tranny you can do a rear end.

That was where I got the parts to rebuild the Power Lok in my truck. I didn't need the spreader to get the diff in and out.

 

A big deadblow hammer will do the job. Since yours was not a complete rebuild it probably also went in easier being worn.

Is a D70 like the smaller Dana axles where the shims are inside of the carrier bearings? If so a set of setup bearings would be nice so you don't have to press them on and off to change shims. If your old bearings are in good enough shape you can grind them out on the inside and make your own set.

 

hmmm, I'm doing my d70 this week---i like the idea of setup bearings made out of the old ones. Will I need a case spreader? I did the front d44 on my w150 last year and used a huge soft mallet, but I got my 70 apart and wow! those pieces are BIG

 

No you do not need a case spreader. It would be much easier if you had one though. I didn't use one on the Dana 80. A dead blow hammer and some sweat did it.

dont put in 3.55's you want some 7.17's in that slug for some highway cruising...... he he. jiMMy

 

yes the shims are inside of the bearings.

 

That'l help the Mpg.

 

thanks for all the info I think I'll pass on the 7.17's for now I've done a few 44's but this will be my first 70 & 60 I hope the deadblow hammer works I'll let every one know how it turns out. Ken
