Re-gear pricing?

Recently getting some quotes for re-gearing from a ring & pinion 4x4 shop, $800-900 per axle including all new high quality gears, bearings and seals. Does this price seem fair/reasonable?

Thanks
 
Probably a little regionally dependent, but that's not bad. That's about what we charge and the 4wheelparts an hour away gets about $1500 for G2s.

This is what's on their website: Revolution Gear & Axle, G2 Axle & Gear, USA Standard Gear & Yukon Gear & Axle. We also offer products from ARB, Dana/Spicer, Eaton, Detroit and more.

Do you recommend G2? Which one is the best?
 
Not a bad price. For gears, I love the factory Dana gear. Super to set up and just quality all the way. Of course if available in your ratio. The Revo gears set up nice as well. Realistically, most all gear sets are good, many cut in the same factories, so I wouldn't rack my brain deciding which brand. Set up is far more important.

Shops usually quote a higher price than they'll actually accept if you push back saying it's above your budget, being firm by saying something like you can't spend that much. Offer them $1500 total and see if they won't come down if they see you'll sign the order with the right discounted price.

If it were me, I'd specify RGA gears and then tack on $120 to get them treated with the REM process (available from RGA) which will eliminate the need to break the gears in and they'll last longer to boot.
 
Based on the regear job I did myself , and all the aggravation of getting the kinks out .I'm almost at the point of saying no price is too high if it's done right. I know that's not realistic , bit i'm exaggerating to emphasize a point .

Sir, I commend you both for regearing and hiring a pro.

You will love the regear , believe me. If I bought a lifted Jeep today with oversize tires and stock gears , I doubt I would even take it home before I sent it to be regeared.

I paid $1,800 out the door for parts and labor so that doesn't seem bad to me.

Whats REM stand for and what exactly is it and are you referring RGA Revolution Gear Axle company?

That's what I was quoted , but I outsmarted them , and tackled it myself . I 'll likely have 3,000-3500 hundred in it before it's right.

Maybe more if I work on it myself again .

My quote from Jeep West was $1400 total for both axles (700 for Yukon full re-gear kits front+rear that includes new bearings+seals and 700 for labor). $1600 total is not too far out of range if it's a reputable shop who will stand behind their work.

Revolution is highly recommended here. However from what I understand, the gear set-up matters much more than the brand of the gears themselves. As long as you get a high quality set (Yukon, Revolution, G2 etc) you'll be fine. Note that most shops prefer to supply their own parts for warranty reasons but there are shops that definitely will take your parts and install them for you (which is what @Chris ended up doing).

And not to scare you, but beware that there are a few Jeeps that are probe to developing driveline vibrations after a re-gear. You'll know only after you regear, no way to predict beforehand. Happened to @Chris, myself, @Ranger_b0b, @Mr. Bills and others. The solution is not very clear, each Jeep seems to present slightly different problems.

Many if not most quality gear shops will refuse to install customer supplied parts. The shops that will install customer supplied parts typically won't warranty the installation labor if the parts fail for any reason. For this reason it is more important to pick a reputable shop than a particular brand or gear supplier and wise to let the gear installer supply the parts. If a particular installer favors one brand over another go with the installer's advice rather than Internet advice - there is nothing magic about Revolution or any other major brand - all will provide good service.

Harmonics or vibrations after a re-gear seem to be isolated to TJ's/LJ's with the 241OR transfer case after re-gearing to 5.13 and 5.38 ratios, however there are some reports of issues in jeeps with the 231 transfer case and/or with 4.88 gears. The current working theory is that the angle of the double cardan joint in front driveshaft in combination with the driveshaft length can create a harmonic at highway speeds due to the increased driveshaft rpms after the gear change. The harmonic isn't noticeable with taller ratios because the front driveshaft doesn't spin fast enough until one is at very high speed, typically faster than anyone can drive their jeep. My harmonic comes on at about 67-68 mph, and was reduced substantially by adjusting the front pinion angle so that the front driveshaft and pinion angles matched exactly. It is barely noticeable now. There was no vibration or harmonic when my jeep had 4.88 gears.

Totally agree on your 1st paragraph. The installation is far more important than the brand of the gears.

I have vibrations (not quite sure if it's harmonic) that developed when I went from 4.10-->4.88 (241OR TC, TJ Rubicon, 42RLE, 265/75R16 tires, 2.5" lift), so it is not limited to 5.13 or deeper gears.

Odd how some get them and some don't. My Rubicon had 4.88 gearing without vibrations and it now has 5.38 without vibrations either. The harmonic balancer isn't even installed.

Out of curiosity do you lock/unlock your manual hubs when driving or just leave them locked?
 
It's not limited to 4.88 gears either. I re-geared to 4.56's and now have terrible vibes above 60mph, NP231, 3" lift on 33's. SYE, new drive shafts, new adjustable arms, nothing has helped.
 
I'm have contacted a company called Trailtec 4X4 near Richmond VA. They are working with me to come with the appropriate gear to tire ratio for my Jeep and what I want to use it for. So far so good they seem to be very professional. As of right now it's looking like a 4:88 would be a wise choice for my 4 cylinder Jeep with 33" tires. Trailtec comes highly recommended and it is said that the owner is very trustworthy and honest. Trailrec is an authorized dealer of RGA gears which personally I've never heard of, I always thought DANA was the cat's meow. I recently emailed Trailtec asking about the REM surface finishing that Jerry recommended and expressed concerns about Harmonic and/or drive line vibrations. Since this is my first re-gear I did not know about a lengthy break-in process so the REM surface finishing sounds like a great idea and for $120 money well spent.

Thank you to everyone for all of your input & suggestions. I'm probably a couple of months out before taking my Jeep in for this up-grade so if you think of anything else please feel free to keep your suggestions coming.

Sincerely

Bill

I think you'll be disappointed with 4.88 and 33's on a 4 cyl. I run 4.88 with 31's, also in a 05 SE. Works great but would need more gear for 33's. The 2.4 just does not make any torque until 3k which is where it should run at 70 or so. I am currently 3100 @ 70.

Will 4.88 be better? Hell yea. But it can be better with 5.13.

Oh, Dana gears are the cats meow. One of my favorite to set up. The Revolution gears are also a nice gear to set up.
