Help
Hi I have a 7.3 Ford Excursion 2 wheel drive with limited differential. It started having a whinny noise from the differential. Ford dealer told me it’s going to cost $1600 to replace worn ring and pinion gears/ bearing/ axle seals. I’m pretty sure I can do it myself. Where can I find cheap parts? HELP!

well all that is fine but the thing is that $800 for parts alone is b.s. ring gear pinyion , and "rebuild kit" wich i thik is way to much ." i knoe because i was a ford parts guy along time ago and was a mechanic for 1 year before i joined the millatary but now i dont have that much time to do things like this so i took it to a ford dealer and told them to findout whats going on LOOKS LIKE I WILL HAVE TO MAKE TIME
also maby now is the time to change the gearing perhaps a little taller for lower rpms on hwy any who i will have to do it myself next weekend if i can get parts soon enough and cheep enough

Hard to find a dealer who is willing to put in gears in a size that were never a factory option. 3.55's, huh? If you think the turbo lag is bad now...

Dropping those gears to 350 is going to drive you crazy. As it is the truck lags with out modifications and now lowering gear ratio it will be slower then a yugo. Keep your 373. The truck is to big to go any smaller. Those are actually a little to small for this truck. Nebmike that is a great price you got for Yukon 4.56's.

My total bill came in right about $1550 to swap from 3.73's to 4.56's. Thats two gear sets and the associated materials/labor. $1600 for one axle (and the rear is easier than the front) seems really expensive! Several people in here have commented on getting BOTH axles done in the $1600-1800 range.
I couldnt be happier with the set-up now! I wish I'd done the swap a year sooner!
Stealership, for sure!

I really wish I'd done the gear swap before the Banks system... I'd have about $4k more in the bank right now.
The gear swap gave me exactly what I was looking for in terms of performance.
