Ever since my rear went out in my 05, I have been looking for a lower-cost replacement that I would not have to deal with the dealer for.

The ring gear lost 4 teeth so it just won't go for long without getting stuck on the stripped part of the gear.

I removed the differential "chunk" and took the ring gear out, thinking that was all I had to do. However people tell me I should replace the ring and pinion gear, oh then I also better get a crush sleeve, pinion seal, two new bearings all ordered through the dealer... so much for doing it myself. Already over $300 spent and now the guys at the shop are telling me the pinion gear is too short!??!!?
I was told that I have a: " OEM TOYOTA 4 RUNNER REAR AXLE DIFFERENTIAL E-LOCKER 3.73 (3.727)"

Anybody know where I can just order the whole assembly or what other ones might fit my 05 without causing any other problems??
If anyone can help me please and thank you!
