The seals are similar, old seal spins on housing, new seal is stationary on housing and spins within itself. Sleeves were used on the old type seals and interfere with the new type.

Maybe as simple as the wrong bearing gap/lash setting. You do have to slide it over the end without crunching the spring or damaging the seal face.

Roland,remember the rear seal area gets the oil from the differential,would definitely check the oil level in it before driving too far,you have no way of knowing how low it is.

John am aware of the lube process back there. I can't even have the thing towed to a repair facility. Haven't moved the coach a half inch since we stopped last night. Leaking seal is bad enough don't want to have to replace the whole rear end. Folks that replaced the seal yesterday are sending someone out to put in a new seal at no cost to me. See how this is gonna work out. Going to make sure they fill the differential.

Keep us informed.

Craneman, good tip and helped Roland get the shop out to fix it. Probably oil not low but check for sure. It's on them!

OK the outfit that replaced the leaking seal in Carlsbad had a mobile outfit from Las Cruces come out here too replace the seal at no cost to me. So this guy shows up in a Chevy van and I'm thinking ya gotta be kidding me. He had a compressor in the van and all the tools he needed except for a press to press the seal in. But more importantly he knew how to do the job. The seal that he removed was bunged up and was not properly installed. (The mechanic in Carlsbad did not seperate the disc from the drum when he installed the seal. I was not familiar with how to put the seal in, but I did remark to my DW that I didn't think I liked what he did.) When the mobile mechanic finished he added one and a half gallons of ninety weight oil so I was down quite a bit but not enough to mess up the bearings or differential. Guess it was good fortune that I stopped when I did last night. So tomorrow I will head towards Ajo and keep an eye out for any more issues with that seal. Will let ya know how it all works out and will then do the reveal on the names of the outfits that did the work at that time.

Glad you are able to be mobile again, sorry that you are having all these issues at once. When it rains it pours, hopefully your umbrella is nearby.

So in retrospect next remark to them it does'nt look so good or at least ask the guy how many seals he has installed,if the answer
is 0,watch like a hawk.

Arrived in Ajo late this afternoon. Going to get under the coach and check the differential level. I suspect the seal is leaking but that's just me. I'll check on Monday and let ya all know

Glad you made it. Might also check the oil in the rear end, a gallon and a half is a lot of add oil even with a seal leaking.

I hope you are wrong. The other (bad) seal leaking that much lube must have made a real mess on your wheels, tires and axle. At this point I don't know how you would be able to tell if the replacement seal is also leaking.

Yeah , that's why I have to crawl under there on Monday to check the level in the differential. The seal that was leaking badly was all bunged up. The technician, and I use that them loosely, took a shortcut and did not seperate the drum and disk when he installed the seal. Lorenzo the mobile mechanic told me that it was impossible to tell if the seal was seated correctly doing it that way.

You may also want to see what that diff has for a vent and make sure it's not plugged.

With the miles that we run compared to OVR trucks, the old style seal that pushes into the inner end of the hub should work fine. We should not have much if any grooving on the axle stub. This is easy to install with the drum or disc still attached to the hub. You have to guide the hub onto the stub carefully for sure but it seams to push on well.

While maybe a Superior seal , the two piece non rotating seal, stands a good chance of being ruined each time you remove the hub IMHO.
Second on the axle vent. Check for sure .

Well I crawled under the coach yesterday. Differential was down a quart. That's one quart for 375 miles. So the seal is still leaking. Am wondering if I have the correct part number. I got the part number from Foretravel, but the drum disc brakes brake cans etc were all replaced last summer wonder if the seal is different then OEM. Seems if the axle vent was at fault both seals will be leaking.

Not necessarily on the axle vent and both seals leaking, the weakest seal will fail first and relieve pressure. Drove my coach home 1400 miles and did not check differential lube because there was no evidence to suspect it might be low, and had been serviced. Got home and discovered when I pulled the level plug that it was overfilled by TWO gallons. The only thing I could figure out is the tech filled thru the vent opening.

Might try getting the tag I'd # off the rear end and check with NAPA. I doubt the seal is special to Foretravel. Don't quote me but seems like mine are something like 37001A. I'm not at the coach for the next week so I can't check it. With that said it would hard to install the wrong seal. I agree with you something is not right. Installing axle seals is basic 101 in truck world, not rocket science.

Do you see any leaks? Were you level when you filled? Level when you rechecked? 1 quart is almost nothing it could have just been down in axle tubes. You should be able to see if oil is leaking still.

1 quart could be a heat expansion difference.

Re: Failed Transmission cooler

Reply #71 – November 09, 2018, 09:06:06 am

Loosing one quart of oil while driving would make a HUGE mess and you would smell gear lube just by walking around the coach.

Sitting with the fill plug a little high would easily account for a reading 1 quart different.

Yes I smell the differential oil when I walk behind the coach. And yes it made a &_$#@ mess on my car. And no it was not overfilled by the mobile repair technician. And yes the seal is still leaking and that's why I believe I have the wrong seal. I will call Dickensons in Indianapolis next week too see if I can get a seal part number from them.

Will try and find a parts breakdown we can look at,unless you trust that place with your life my thinking is one shop put a wrong
seal and/or installed wrong why should another one be any different.Also Roland,I remember the Stemco webb site did have some
install videos,may be worth looking at.

Plan on bringing the coach to Rush Truck repair outside of Phoenix to replace the still leaking rear seal. Anyone ever heard of these floods. This is my last go around with this seal.
