Good afternoon!

Over the past few weeks I went through a whining sound on coasting/decel coming from the rear differential of my 05 Jeep TJ. I took it to the shop where I was told the pinion nut loosened up and that the inner workings of my rear diff are all pretty damaged, ultimately recommending a rebuild.

Current setup: Stock Dana 35 with 3.07 gears, 31 x 10.5 in tires, no lift
Quote to rebuild what's there: $500 parts, $1500 labor

Question 1: Is this pretty standard for a rebuild cost?
Question 2: I don't really wheel and plan to mainly use the jeep for occasional light trail use, if snow is pretty bad on the roads, etc - Is it worth pursuing a Super 35 rebuild + or - regearing to 4.10 at this price point? Only planned upgrade is maybe a 2 in lift and replacement of shocks/springs etc if they go bad.

I appreciate any thoughts or input from y'all!
 
look on facebook marketplace for a stock 35 in 3.07 gears for $100 bucks. They regularly are sold for that around me. Swap it in and use your other $1900 to do all the other stuff you want to do later on once you get back on road.
 
What parts are they quoting for the $500? And that labor cost is way too high for a rear axle rebuild. Should be about 5-5.5 hours total.

Good advice, I think. Lots of folks pull perfectly fine stock Dana 35s when building for bigger tires. A super 35 is overkill for your intentions and only can be done with a locker which you wouldn't need either. The price of the labor does seem high to me as well but everything seems to be shooting up.

Way too high. Look around for a 35 3.07 take out, or find a set of axles with a better ratio like 3.73 or 4.10. In my area you can find a good 30/35 3.73 combo for less than $1,000.

Parts: new 3.07 gears, spider gears, and master rebuild kit
Labor: quoted at 15 hours
 
You can save yourself some money if you take out the rear axle yourself. Take out, remove axles etc.
But more work and not really needed for most/good mechanic to switch gearing. Labor should be more like $500.
 
Had both axles regeared last month for $2,000 total parts/labor. Keep in mind I’m in SoCal where everything is excessively expensive. Labor costs should be materially cheaper where you reside.
