DIY Regear

[LoJac963]

Evening everyone. I have been reading a ton on DIY regear and am considering giving it a shot since the truck is not my daily and can be down for as long as needed?

I do all my own maintenance and repairs on all our vehicles and always have. Never tackling a regear but have the press and most of the tools to give it a shot.

My question is, it seems Revolution is the go to for gears and instal kit but why does no one go with Spicer? Spicer is what they come with from Dana. Just curious if it's worth the extra $100 to go spicer?

Thanks!

Mine has spicer 5.13’s. A shop put them in in 2022.

I’m quite interested in the process, and would also like to do this someday. Please keep us posted.

I did a regear and lockers a few weeks ago.
I used this kit from Northridge that included the rings, pinions, and Spicer rebuild kits.

As for the price difference who knows.
It took me just about 26 hours total including some food breaks, a parts run and a tool run. I also dropped my axles all the way out to do mine, as well as ran all the ARB stuff. It's not unreasonable to do in a weekend if you plan a little better than I did.
(or just wing it like I did and do it in a weekend anyway)

I got my 4.88s done with Dana Spicer with the coating so there is no break-in. All done in a few hours by a great shop. $1900 total. It was well worth it not to need any hand cleaner. Gears are a real art, you get one chance to do them right.

Imo. Spicer gears is easier to setup. Make sure you have all the needed tools on hand. 1-3/4" dom tubing can be use to press in the pinion head bearing. If you're tackling this by yourself than i highly recommend a 1.5"Dia x1.5"L steel tubing to help with getting the pinion through the tail bearing, so you will have some threads exposed for the nut once flange in place. Also, torque the 4 axle flange nuts in a crisscross pattern to avoid pitching the seal, silicone grease works good.

I'll second that about the Spicer gears. I've installed other brands of gears that looked like they were "machined" with a cold chisel, the Spicer gears were a work of art by comparison.

I just had my JT regeared with Spicer gears. I figured going with the OEM vendor makes the most sense. My installer was very impressed with the consistency of the new gears compared to everything he was taking out. Said it made the job a bit simpler than going with aftermarket gears.
Also, Spicer Dana told me there is no break in procedure which is another added bonus. Just avoid towing for the first 500 miles.

One thing that gave him trouble on mine was the front carrier. He couldn't get it out. He had to physically cut the races out of the bearings to get it to release. Going back together was basically like starting from scratch.

All in all, it went well. I have just over 200 miles on it so far and everything is good so far. Might swap gear oil in a couple hundred miles just to check on things.

Spicer is by far the preferred gear set for these, least amount of whine and problems. People only go with revolution because Spicer is often hard to find, and revolution is the 2nd best/reliable choice.

This is so true. When I did mine they the stock ones I pulled out were marked 0/0 and the new ones I got marked the same. Basically didn't have to adjusted the shim packs because of how consistent they are.

If you are tackling your own, definitely go with spicer.

I worked at an off-road shop in college, did a handful of gear swaps with the mechanic there looking over my shoulder.

Dana Gears are all "supposed" to be 0-cut form the factory, meaning every dana gear put out regardless of the ratio should use the same pinion shim for correct pattern. You can confirm this when you get your new gears and pull our out factory gears both should have "+/- 0" stamped on the pinion. As long as they both do, in theory you should just need to measure your factory shim thickness, match that with the supplied shims in the new install kit, and button everything back up.

Pattern- Even if they are both stamped 0, i"d definitely still run a pattern. Keep in mind the Dana gears will be a 2-cut gear vs most aftermarket companies being 5-cut gears, so the pattern is read differently. This link has some good info about the difference between the two: https://differentials.com/two-cut-vs-five-cut-gears/

I've setup a bunch of different gear sets in different axles (Dana, Ford, Chrysler) and I would say Spicer is the easiest and fastest, particularly in these Advantek axles. I ended up using the stock carrier shims in the front and rear of my axles and just added a few thousandths to the pinion shims on each based on the pinion markings and stock gear shim thickness. I called it a day once I saw the pattern and threw everything back together. They are quiet too, at least compared to some Yukons and USA Std sets I've used - there is definitely a difference in manufacturing vs other brands.

$1900 all in? This sounds like a bargain to me.

It was pre-inflation. Premier West Gears in Riverside Ca. They do a lot of gears.

Gears aren’t a place to cut corners. I’d definitely go Spicer for Jeep. The reason people didn’t use them in past years was they only offered whatever ratios were OEM. Over the past ten years or so they’ve gotten deeper into the aftermarket, with more gear set offerings. The best used to be Yukon Gear, but since the pandemic it seems they’ve slipped off the radar.

Would likely be a long process for me as well since this would be first go at it.
