Needing a new rear end - Need Some advice
Another member recently posted a video of a noise his truck was making. Turns out its the same noise I'm dealing with, except I'm out of warranty. The dealer says a tooth broke off of the gear and ended up replacing the whole rear diff assembly. Out of warranty cost a little over $3000.
So my question is, what are my options for upgrading. I do plow snow, I do pull a 4,000lb trailer at least once a week, and I do a little bit of offroading and am tired of the one-wheel peel.
To start, I know nothing about rear ends. I can do a fluid change and thats about it. I've researched a little on here about auburn LSD's, ARB Air Lockers (I already have an air horn setup), and the famous 4.88 gears available (35 x 12.5 tires coming this fall). But this truck is my DD, so 4.88 gears scare me a little with gas mileage.
What are my best options, aftermarket or OEM. If the cheapest way is to spend the $3000 and get the toyota parts, I guess thats my answer. But if I can get a locker for $3000, why not? May as well upgrade while its getting replaced. I don't want to end up spending the $3000 for the toyota parts and $1500 more for a LSD or locker.
I'm just looking for a list of options, as I have no clue what I am looking at. Install would be done at a local offroad shop, since I am not ready to tackle this project.
Sorry for the rambling post but thanks in advance for the help!
