Coast side noise suggests pinion bearing issue. Bad preload or just defect causing bearing failure.
Edit: more specifically, I’ve had coast side noise at speed twice and it turned out to be insufficient pinion preload. But that was not on a Ford diff, so I’m not sure if my experience translates...
Any idea when you’re getting more in? Allegedly mine was shipped by truck almost 2 weeks ago. My wife leaves the country in July, so I’d have to get a dog/house sitter to fly out there.
If it were that easy, it wouldn’t be a lemon, right?
Maybe delivery time of replacement parts made it qualify. But knowing how hard it is to get a buyback, I’d never touch one. I’m salty from prior experiences with Ford and Subaru though.
Sounds like a pinion preload issue. Did they provide full setup measurements or just the backlash? This is common in the Jeep world I come from. Proper backlash and pattern are only half the equation to proper setup.
I’d use the thread count as more of an extra layer of confidence, the torque value seems more definitive as long as it doesn’t get hung up early on something.
I recommend counting threads too before removing. Extra insurance to avoid preload issues. My experience is not from the Ford though, so may be irrelevant.
My tracker still shows in production, but I got an email it’s built with a new delivery estimate. Off to Des Moines at the end of June now, I hope. Mid-June delivery estimate.
Yeah, I was planning a month too. Then Ford and the dealer told me to be ready the 2nd week of June. I’ve never heard of one taking more than 2 days after their blend date to finish production without being for a QA/QC failure. I have heard of them being stuck waiting for shipping up to a month...
Well, in spite of being stuck ford performance chat has an estimated arrival date range of 8-14 June at my dealer. Time to plan my time off. I’m trying to confirm with my dealer, but I won’t book air tickets until it actually arrives.
A good forecaster will use unconstrained demand, not sales to forecast optimized allocations. The trick is to avoid garbage data like cancelled orders or anything else that can inflate demand per dealer in a way that won’t translate to sales.
No idea what Ford does, just projecting my experience.
