Thank Gawd for JiffyLube

I never thought I'd ever be saying this, "Thank Gawd for JiffyLube." I took my new 99 F350 into JiffyLube for an oil change and during their gazillion point check process they discovered that the cover on the front differential was bent and appeared to be leaking oil. Not good, since I just bought the truck and it had previously been sitting for 3 years, dented cover and all. JiffyLube pumped in 3.2 quarts of gear lube into the differential. The rear differential tool 3.4 quarts.

So I went to Summit and bought a couple of cheap covers and a bunch of Lucas gear oil.

I have noticed a significant amount of oil underneath that differential. Not pouring out, but certainly enough to drain it dry over the 3 years the truck was sitting.

So while I was underneath the truck drilling and tapping a hole in the exhaust manifold for the egt probe, I went ahead and popped the cover off the diff.

Not good.



Sorry for the bad picture, but all I had was my phone. However, it's clear that I have issues on both sides of the gear teeth.

So how hard is it to do the gears on one of these? I've got lots of experience with setting the lash on spur gears, but I've never done a set of spiral bevel gears.

Anyone have a good source for gears they could point me to?

Anyone know of a good source for instructions on how to lash these?

I shudder to think about what I'm going to find when I pop the cover off the rear diff.

if you don't change your oil i wouldn't get into this. unless of course you just don't change your oil, because it's a job to get rid of it.

Nah, it's not that I can't change my own oil, it's more that I've reached an age where I don't want to change my own oil. As a former mechanical designer and machinist I'm pretty sure I can figure out how to lash the gears, but I've never actually done it on one of these. All the machinery I designed used spur gears or helical gears. When you put the spiral-bevel into it, it becomes a whole new set of specs to take into account. I'm not sure I have all the tools and tricks to be certain everything is right. Right or wrong, it's still the first time for me, and I'm a believer that experience trumps education any day of the week.

Plus, as you might have guessed by my username and avatar, It's a little tough for this old fat guy to climb underneath a truck, (unless it's one of those monster trucks that is.)

Just gonna put in my .02 from semi personal experience (didnt happen to me, I do all my own work, happened to a family member) Stay away from Jiffy Lube or any of the Quickie Lube places run by drug addicts with anything you want to drive for years to come. If needed, I can go into the long list of details, but I think you understand where we're coming from here.

You spent the money on the truck, spend the time taking care of it so it can do the same to you

Otherwise welcome to the org bud

Here's the tag info off the front differential. I'd sure like it if somebody can tell me what I have here, mfg, model, gear ratio, and anything else that might be significant.

4.10 ▼F81A AYL
▼ 610655-2

This is the front differential. I bought the covers for a Dana 60 and it did fit, but I still really don't know what I've got.

This truck is a 99 F350 SD Dually. It has a build date of 6/98.

Oh yeah, I agree, but I was in a hurry and had a ton of stuff going on at the time, plus the old lady had a coupon. I'm very happy to have joined the PowerSmoke club, but I've long ago lost the thrill of working on (any) vehicle. I am enjoying learning about the truck, and I'm enjoying the modifications I'm making, but if I had the money to have the shop fix this, I would have it there in a heartbeat.

Your gonna need to get a install kit for what axle your doing. Your gonna need a dial indicator for backlash setup and some gear setup paint to set the teeth up on a wear pattern.

If your changing with the same gears, USUALLY you can use the same shims on each side of the carrier, but get new ones new carrier bearings ETC.. Setting up a rear is difficult. Either if pinion is to tight it will whine or if its not it will howl.

Its more time than anything else. Try your local wrecking yard and see what they get for a axle instead. Shops will charge around 1500 bucks usually to tear down a axle and rebuild it. Sometimes you can score a whole new rear axle for 500 bucks.

IMO if it aint howlin or whining or chattering keep running it. Either way if you blow the parts out the diff cover its still gonna cost the same if you took it apart now.
