took apart a ford 9" differential to install a locker. got lazy and tried to find a shop to set it up. first place I called was an axle shop that was recommended plus they did some Jeep work for me in the past. no dice. they didn't wanna touch it. tried two more shops. nobody wanted to touch it. fine. my 13 year old and I started through the process: backlash, preload, we checked the pattern: coast was perfect, drive side was low and too much to the heel. my 13 yo son finished it today by himself;

so.... If a 13 year old can do it, why don't shops wanna touch it?

They don't want to be responsible for something that you could mess up after it left their shop.

It would not have been an unfinished job. they would have gotten a complete 3rd member/carrier with all of the pieces in it. they could have replaced the bearings and done a complete rebuild. 3 bearings and all of the setup. how is this any different than removing a transmission or an engine and taking it for a rebuild.

It's not installed in the vehicle yet? I wouldn't declare success just yet.

I would have done it for you, 9" Fords are easy & I'm very familiar with them.

I only warranty against gear noise if NEW OEM or Yukon Ring & Pinion set are used, No warranty on overheated gear sets from incorrect break-in/overloading/fluid level, No warranty from damage caused by contaminates that came from the differential axle housing on carry in 9" center sections (not my fault the housing in your car has a pound of metal shavings in it), Last but not least.....No warranty on customer supplied parts.

If I build the differential from scratch, Buy the parts, Install it, Break it in.....I give a 2 year unlimited mileage parts/labor/noise warranty (minus the gear oil).

sounds good to me! all new parts that you source? fine! Yukon gears and locker? fine! I'm not looking to save pennies here - almost everything else on the car is new and improved: engine, transmission, wilwood brakes, suspension, all accessories. there's only 2 parts under the hood that are original: the distributor hold down, and the oil pressure sensor adapter. only thing left after the rear end is steering.

Race shops will do it, at Race Shop labour charges, which can be less than ordinary car shops but at worst, no more. Talk to the racers in your area and they will put you on the right guys.

Don't know if it's still around but we had not far away a dedicated differential shop.
Although back then they generally didn't accept customers bringing in parts to use.
Another shop up the hill would do complete rear & front ends mainly for the off road crowd. Had complete units lined up on the floor all clean & pretty ready to go out the door. Just no mounted wheels/tires on them.

What type of locker?

Full carrier locker or a detroit/spartan/aussie auto locker?

I'd check if there are any off road shops. Any off road shop should know their way around differentials.

It's hard to find good shops that aren't just parts swappers. They are used to someone coming in with a blown up rear axle that they can just swap a junkyard axle with. Much easier to do and can still charge a bunch of money. There are a few really good professional shops around here, and they are constantly busy for that reason. I agree with Miller88 that your best bet would have been an offroad shop.

It's time consuming to do a setup correctly. Lots of other quicker jobs to make money on. Even setup correctly it may have noise. Most shops don't want the potential hassle.
