Well i broke some teeth of my ring gear the other night while pulling. I guess it all unfolded when i broke my driveshaft. Although snow flake still gets from point a to b i need to replace the rear end. What should i go with


My thoughts

A mini spool with 4.10 gear ratio. What do yall think. Although its a pretty penny i gotta do something to get me back up and pulling and driving soon

I would say the 4.10 is a good idea, but if you pull a trailer or haul a lot of weight in the bed with it the spool will become a problem eventually I would say.:)

When you turn a corner the inside tire turns slower, and with a spool they have to turn the same speed. That makes the inside wheel spin when you turn, when you put extra weight in the bed it puts a lot of strain on the axles. If the axle hops it could in theory break an axle, but would for sure wear bearings and tires a LOT faster. And it's extremely annoying to drive on the street with a spool.:D

Don't waist your time on a spool. Your diff is already screwed, have a good welder weld the axle gears to the 3rd member and bam, you still have troubles as you would with a spool. Just a little cheaper. But there is a plus side, that money you would have spent on a spool can now be used for the parts you'll break and wear. :D

I've read on the DP when I was looking into gearing that Thorsen's rear diff wasnt too bad, but then I read they go out too....Let us know what you decide!

Kurt,

Sorry to hear about the rear end going out. i didn't see where we established which rear end you had? Corporate or ?

Unless the technology and design criteria changed you would be better served with an aftermarket ring/pinion and welding as mentioned by Mike. My opinion, I have an ass to.:rofl:

My opinion is based on the following. If you have a corporate rear end there isn't much that's stronger than what you have in terms of the lim slip. The other options offered work more consistantly but aren't much better in terms of strenght IMHO. That being said i would weld it up if you don't haul loads and turn left and right.:) As for the ring gear... Generally a factory gear is physically harder to create length of service, this is it's performance downfall, it has little give when you beat on it. It'll break. A performance gear is not as hard and will give a little, "flexing" of sorts similiar to the Golden Gate Bridge, it doesn't fight the earthquake, it gives with it and lives to see another day. I build structures that sit on monster ball bearings so they move with the quake versus being shaken to the ground, same type of thing. You can still break the gear but it'll take a more effort and subsequently wear faster.

Lastly... perhaps you just wore it out? Have you looked at the surfaces to see where it's landing? Is it perhaps whining a little?

Thanks for the explanation James. Fantastic.

I think he has some missing teeth on the ring gear.. or pinion... :eek:

oooo, tone down the tune guys!:rofl:

I recently heard of a dragger who "hooked up" at the strip and turned the 3/8" wall housing from the pumpkin!! Jesus Christo that' some grunt, anyway welding the pumpkin to the shaft has become an option, bring the HEAT.

Thanks Mike.

Damn, and I thought I was badass when I took out 3 different ring gears in my firebird after I went to 4.10's. 12-bolt fixed that for a while---then I ripped the torq arm apart :eek:

I wouldn't go with a spool on a DD. They are scary in the rain! :eek:Just put a Detroit locker in, you will be much happier. With a spool you will also have the turning radius of a bus..lol
