Regearing and Locking Diffs

[duderz7]

Does anyone know if any of the years past 07 would have 4.10 gears? I wouldn't think they changed the suspension that mich between the years

If I recall correctly, I don't think they continued making the 4 cylinder Liberty pas 04 or 05 due to low sales.

Not what I was told when I called a few yards. I'll take your word for it since you were/are directly involved. Anyhow, nobody had any 4.10 anything on the site...yet, they did?

Some could be so backwoods on their operation they don't do immediate inventory on receipt of the vehicle.

Even if they do, there's also a possibility of unknown details/options. Gets lumped in under the usual 3.73 stock until the diff is physically checked over and inventory is updated.

Anyway, I see the Yukon 30HD 4.10 gearset is back on Amazon

this would be for front differential?
and then rear is easier to find?

Maybe, maybe not. A 4cyl Jeep XJ or 4cyl Dakota might have 4.10.

Yes, and they could potentially have a dana 30, but the dana 30a is what is in a kj and no other gearset fits it. The pinion gear is shorter.

I was commenting on the rear only in post #24.
