Oil on inside of rear tire and rim

December 09, 2019, 05:01:19 pm

Was crawling around under the coach yesterday with a grease gun trying to hit the drive train zirks and noticed the passenger side rear rim and tire a coated with oil. I assume this means a seal needs replaced.

I try to do most of my own work, but suspect this job is beyond my level of experience. Has anyone done this themselves?

Any suggestions on where to get the work done in the Dallas TX area and estimates on typical cost to do this kind of repair?

I have not had to do one on the coach, but have changed many axle seals on trucks. They are the same. Most on road truck repair facilities can do the job. If you are going to tackle it yourself PM me and I will give you my number and I can walk you through it.

Thanks Cranman. I think I will check with a couple shops for estimates, but prefer doing my own work when it is practical. Removing those tires is a bit intimidating.

Got to one of the shops in Naco. I do not know if the caliper will have to be removed, but after all of the problems I had with brakes I am gun shy of getting someone to work on my coach. I had taken our coach to three places in Houston and they all said they worked on big trucks and it was no big deal. Only problem is they did not know about the disk brakes on our coaches. Even had a shop that worked on Firetrucks that have the same brakes as our coaches screw the brakes up.

Problems I had were they did not know the pins were they took them apart, put the wrong grease in, and did not adjust them correctly.

Here is a picture of what they look like. The caliper can be rotated out of the way to pull the rotor. Still have to rotate it the opposite way to be able to clean both pins and install the helper springs. With the rotor off you can see the seal in the back of it. Dealing with the wheels takes either a specialty tool, plywood with grease or big muscles. The rotor is not that heavy.

Removing even the rear tires/wheels is easy with just a few tools. I just bought a torque multiplier off ebay Torque Multiplier Set Lug Nut Labor Saving Wrench Remover Truck Trailer RV... It's built like a tank and the model I purchased had lots of sockets with it. About $10 less for the model with fewer sockets. You will need a flip socket probably like the one I have in the attached photo. Less than $200 buys a 20 ton hydraulic air jack (on sale), flip socket, torque multiplier, 110V HF impact driver and a few other small items.

Below is a video of the operation of the torque multiplier. Once you loosen just a little, a $39 Harbor Freight 110V impact wrench will spin each one the rest of the way in less than 5 seconds. I use a little Anti-Seize Lubricant on the threads so only re-torque to about 340#

I don't even drive to the bottom of our driveway without a spare tire onboard. It's really easy to change, especially important if out West where cell service is iffy. You do need the safety equipment so read up about that.

Before you go buying expensive tools to remove your rear wheels, look for cradle to pull your rear wheels in one shot. All you do is loosen the 8 nuts that hold the axle shaft in, with the shaft out of the way it's time to back off the bearings nuts. With the axle jacked up so the dual wheels are off the ground run the cradle/dolly in jack it up and walk the whole assembly out. This is how it's done in a rate shop, where they would never breakdown the rear wheels but pull them in one go as described. It takes too much time to pull the wheels individually. IMHO

The cradle will not work with the disc brakes. Wheels have to come off to remove the caliper.

Perhaps I was unclear when I said this how the wheels are Removed in a rate shop and it's a rate shop that does the repair.
Unless there's some new kind of rear axle out there that I haven't seen, when you pull the axle and back off the bearing nuts the wheels and hub assembly is free to slide out. Having done this on more rear axles than I care to remember including my coach. ?

You will have a really bad time trying to do it that way on a coach with disc brakes. Been there done that. I have removed many a hub with the disc brakes. The caliper has to come off of the rotor before you can slide the hub off and the wheels need to be off to access the caliper

We used a grease up piece of metal or a greased up piece of plywood instead of a cradle and it works great. With drum brakes I would do as Olde English wrote. I haven't remove the hubs with disc brakes and I have the rear duals off my rig and I went out and
looked and I don't see how I could get the brake out of the way with the wheel on so I could pull the hub.

Come on, what does it take to remove the rear wheels, 10 minutes?

Thank you everyone for all of the replies.

If I hire this out, I will definitely let them know it has rear disc brakes.. Should I assume the pads will we oil soaked have have new one available?

I really like the torque converter. Looks like it will make lug nut removal possible without much grunting or large air tools.

How do you use the grease plate? Just drive on it or jack up and slide it under and lower until tire just touches, then "walk" the tire off the lugs and out of the way? I have never dealt with a tire this large.

The grease plate is with drum brakes when you take the duals off with the hub. And yes jack up the vehicle slide the plate under
and lower the wheels just enough to take the weight and slide it off.

Jack up, slide plywood or whatever up under the wheel. loosen lug nuts and lower the jack until wheel just touches and pull off. If you are having it done they will want to change the pads for liability reasons. I know I am going to ruffle some feathers, but I have always been able to use gas or acetone to clean shoes and pads without an issue. But DWMYH

Don't try the greasy plate removing the wheels as you will wear the wheel.

OK, I'm 76 years old now but removing a tire(s) is just not that difficult. You jack up the vehicle until the tire is still slightly touching the ground. With all the lug nuts removed, you just work the front and then rear of the back and forth until it moves a couple of inches out from the coach. This can be done on cement or gravel and does not take much effort. Once it clears the studs, you can roll it to where it is to be temporally stored. It should never be in any position other than vertical. The same for the next tire once you have used the flip socket in the back. In replacing the tire, you roll the tire back to the position where it was removed. You keep it vertical just outside of the studs. Then you lean the top of the tire out toward you a little and work the bottom back and forth until the studs will go slightly into the wheel and then when the tire is put in the vertical position, the studs will be into the wheel slightly. With the tire still on the ground, the tire is worked more back and forth until it is all the way on.

The only thing slightly difficult is removing the spare tire from the storage compartment. I must be slid out until it can be rotated down until one site touches the ground. The higher side in the compartment is already at an angle so not that hard to rotate it to vertical. If the coach is raised to the highest possible position before the tire is slid out and rotated down then there is less angle to overcome.

The tire much be under control at all times. If it were to get away, it could do tremendous damage.

I've done this on my Case backhoe several times with a rear tire many times larger than the 295/75R22.5 our coach has. Again, all this has to be done with the tire still touching the ground.

I use a tire dolly similar to this Torin Truck Tire and Rim Wheel Dolly — 150-Lb. Capacity, Model# TRX01506 |... and a piece of ply wood on the ground to handle the tires and wheels if you don't have a shop floor. This is a good investment if you plan on doing your own tire/brake work.

I use a 2 wheeler to R&R my wheel assemblies. Easily slips under the tire and gives me good leverage to rock the wheel assemble for removal or install. Its also very handy to use for other jobs.

With the help of Pierce, Craneman and the other posters, I have the wheel off, the caliper rolled down, the hub pulled and the seal out. Wow, that hub is one heavy hunk of steel!
When the seal came out, it came out with what I believe is the ABS tone ring. Any suggestions on how to separate them without a press?

Re: Oil on inside of rear tire and rim

Reply #24 – December 28, 2019, 08:16:33 am

My understanding is you purchase a new seal tone ring replacement. When mine were replaced, that was what was explained to me.

There are plane truck seal replacements available but you loose ABS function if you use that seal.
