Anybody want to share, I will say that I have pulled a fairly good size unit, but it was empty, and the F100 rode the best , smooth and quite, only went about 20mi. country roads. Pulled good, but the axle seals went about 2 days later. Also the bearings went out, but looked like they were out for awhile.. Had moisture in the fluid.Pap.
Well, likely the bearings were on their way out, and the added slop then took out the seals/or at least made them leak.
Doesn't sound like the load made it fail...it was already worn out and this pushed it over the edge.
I used to haul a 4000# car on an open trailer all summer with my '70 F100 and never a problem. It had bearings and seals put in it previous to this use. The 9" Ford is a bullet proof rearend, as long as it's in good shape. Using it while it's worn out...will cause problems.
Once you fresh up that rear end, bearings and seals, and change the gear oil, assuming the pumpkin and its gears are in good shape, you should be able to run a million miles on it. The 9" Ford is a great rear-end for a half-ton truck. No problems with strength, trailering, etc.
Pack the bearings in the rearend before you go. Also, for pappie; call AAA and ask because AAA plus does not cover your trailer. If you upgrade to the AAA premier (AAA plus-rv in some states) they will cover the towing for your truck and trailer.
I believe he's installed sealed axle bearings now. And it'd be a tough row to hoe to pull the diff apart and pack bearings in that, 'cause you'd have to install new crush bearings, and then would have to have a dial gauge and other goodies to check runout and tooth contact (under acceleration and deceleration.)
I don't know if he wants to get that involved right now... and I don't know how much experience the man has in setting up a rear-end. Not that he can't do it, mind you ... I did it when I was 16, but I was a lot smarter then than I am now ... :-)
Sounds like a lot of hassle and expense. One thing that might be a good idea, though, if it's showing a bit of weeping, is to replace the pinion seal while the pumpkin's out. 'Course, it might be easier to do it with the pumpkin in, so you can torque against the weight of the truck to pull off the pinion nut (NOT fun.)
Hello SV. Truck is really different, really amazing, and I had done the oil change before the axle, but not the filter as I have to get that wrench, that smoothed out alot, it's great because need her up and running.. I thought might need valve seals because that puff of smoke on start up, but I'm not seeing that now. loh thanks..Pap
