I have a thread going now on my axle whine issues and the inability of the dealer to solve the problem: https://mustangforums.com/m_2020118/tm.htm

So, they've tried three times, and I'm still left with a noticable but faint whine on decel. So, I'm trying to decide on what to do next:

1. live with it since it aint that bad.
2. take it to a different ford dealer and let them have at it. (a local mustang performance shop recommended a specific tech at a local dealer - says he's good with gearwork). If that still doesn't work, move on to #3 or #4.
3. insist Ford pay for a outside shop to give it a shot.
4. be done with ford and just have 3.73's put in at the local performance shop. If I'm gonna have whine, might as well be with upgraded gears.

Thoughts?

I'm leaning toward #2 or just straight to #4. Regarding 3.73's, are they inherently whiny? Anyone have them and have no whine?

Here are some things to consider:

1. 'live with it' is always an option, that's up to you.
2. Worth a shot, I suppose.
3. Not a bad idea, but good luck getting them to agree to this--and even then it's not neccisarily a "done deal".
4. I say go for the gear upgrade as long as someone is tearing apart the rear end again.

By the way, I have had some success quieting down whiny gears using Red Line "Heavy Shockproof" Gear oil. That was in a Toyota 4x4, but I don't see why it wouldn't work elsewhere. You might give that a shot, it's about $8 a quart, and it has limited-slip agent already in it, so it wouldn't be an expensive experiment.

3.73s are not inherently whiny. I have heard that 3.90s are, which is presumably why Ford doesn't sell 3.90s but they do sell most other ratios.

The Ford Motorsport 4.10s I had put in were whiny for about 5 days, then they quited down. 4.10s ROCK!!!

FFRPs 3.73s are made by motive, and they arent installed right, i would just get some FFRP 4.10/4.30s and be done with it
