Gear swap cost

I'm looking as swapping out my 3.73 to 4.88 in my 08 F350 4x4. Going to install a true trak rear diff as well and might do the front if I have the cash. Does anyone know what approximate labor cost would be?

One website I checked showed about 8 hours for locking carrier. I am assuming that is per gear set.

My guess would be at least 1500 maybe as high as 2500. Best go to the shop of your choice and ask them.

must do BOTH or NOT ANY.

4 wheel drive needs the same gear set....

prices will be all over the map.. same with parts. ask the local gear shop.

There were a lot of things I wanted to add to my 2005 f-250. it was cheaper (difference in cash) to trade it in on a 2008 f-350 that had everything I needed.

Sorry if I wasn't clear. The debate wasn't if I going to do gears in both axles. The debate was if I'm going to change differentials in both or just change the rear.

That doesn't really clear it up. You should either just change the gears in both diffs front and rear or do neither.

Also contrary to what someone posted earlier I can't see it taking eight hours to do one gear set, that time estimate had better be for both, with a lunch break.

Ahh I see now. Change it to a true trac as well or just change the gears to match. Sorry for that.

The 2nd " locker" shouldn't add much to the labor cost and should be more cost effective than going in latter to add it.

My ideal setup would be 4.88 with a trutrac rear and e-locker front. What is comes down to is if I need the front locker. I snow plow and my rear LS is shot so a better differential is needed in the rear. There have been time where I have gotten stuck with a front wheel off the pavement and one wheel just free spins while the traction wheel does nothing. That's where a locker front would be nice but don't know if the cost is justified for those rare occasions

A local guy offers some good pricing near me and its about $1,000 for the swap including 2 new ring and pinion sets for a wrangler.

Id like to do this too someday.
