Damn Walmart. I called and cancelled these tires on Saturday because I found them locally. Now I get this email this morning.
I had a fence post bust in the wind, and so I had to tackle that before proceeding on the Mustangs. I borrowed a jack hammer from my neighbor, and now I think I need one. Got it all out and poured in two hours. I used the fast set stuff that you can start putting the fence together in 40 minutes. I waited 2 hours though. I had to do it quick, because I've got stuffs to do! Side Note: My neighbors back yard is a damn disaster.... I also had to cut a vine out, a rose bush, and a random tree. I love my sawzall.
Just got everything arranged so The Eight Nine is the only thing in the garage. I'm going to start tearing into this thing full force! Poor Frankie is out on the RV pad out back.
BTW, the Wife and I made a deal. Frankie gets the garage if she can put a pool on the RV pad during the summer. Kinda foils some of my plans, but it works out.... especially after Frankie gets painted.
Took the 10th Gen F150 on an incline hill today for sh*t's and giggles.
I had a quart of Pennzoil 75W140 with me. It took it all!
This means I have 4 litres of rear diff fluid in there with an OEM rear diff cover.
Unless rear diff fluid gets consumed somehow.
Last changed it on a hoist at shop in Oct 2020.
It was filled with 3 litres and parked for 8 months.
In 3000 KMS I can't see fluid level going down so fast.
Must have been the incline that allowed the extra fluid in there.
Why waste $350 on a B&M increase fluid capacity rear diff cover now?
That one allows 4 litres as well but on level ground.
You may have filled the axle tubes a bit, too. Bearing need a film of oil. Worst case, they may slide and get a flat spot instead of rotating, or make foam, shoving the oil.away.
I did my whole rear, but it is decidedly NOT my area of expertise, theory-wise as to axle bearing lube potential problem, or the yoke bearing, which catches thrown oil. A quart seems like a lot extra.
I did need help to get the new crush washer torqued (~400 ft lbs,) even with a cheater, so the yellow test paint on the gears showed the right mesh. (This sometimes comes with your bearing/crush-washer kit, or is available separately if the company is reputable yet deals with regular joes who din't buy much of this paint. It's an indicator and you hardly need any.)
Over-filling the rear end, especially to that degree, is no bueno. There's a reason for that specified fill level/volume. The oil is intended to be pulled up onto the gears. Having them submerged in it, instead, can cause cavitation and foaming which can in turn rob power and reduce lubricity.
EDIT: As Bill mentioned, oil will likely also live in the axle tubes (and also up at the pinion seal). Don't be surprised if/when any of those starts leaking.
