Oil leak on back of duals
We have been sitting for most of this winter at the Palms RV Resort in Yuma, AZ. I am seeing what appears to be an oil leak coming down the back side of the drivers side rear dual. How big a deal is it to replace an inside rear oil seal? Do I need to go to Prevost in Calf or can any truck repair place do it?

It is a 2 hour job. A word of caution: Torque the large nut to the Prevost specs. Information on the hub nut tightening is found on the Prevost Car web site and different model years had different procedures. The information is in the service manual and will either be torquing to a specific value and backing off a certain percentage of a turn, or measuring run out. Over tightening will damage the bearings, and too loose is equally bad.
Second word of caution: Make certain the bearings are either greased or that the axle is tipped sufficiently to fill the hub with oil. Preferably do both. If the bearings are dry you will get 4 or 5 miles before you twist the end off the axle.

Thanks.

Big dirty job for this DIYer. I did both of mine 1 yr ago. Here’s the thread: LINK

Thx to the info from those that had done it I recently replaced my RH side drive axle seal, along with 3 broken hub studs.
Apparently a success – 30 mile trip for fuel – no leaks, no wheels came off, hub didn’t weld itself to spindle. I did fill the hub with oil AND tilt the drive axle to that side (after topping off) as was suggested.

Prevost Houston caught one front leaking on a Level 3 Service a few years back and had them replace all while i was there. Wasn’t a big cost if I remember.

Nearly every Prevost service (I have no ability for any DIY service) included a leaking seal on at least 1 axle. I don’t get it but I always paid for it.

Yeah mine all at one time (5 years ago) and never a problem since. Have had 3 or 4 level 3’s (service) since.

over a period of 31 years and three coaches I have replaced 6 hub seals. The miles driven by those 3 coaches has exceeded 400,000 miles. I would seriously question how every service requires a hub seal, especially if it is one previously replaced.
I never had to replace one of my replacements.

A truck repair company about 4 miles from the Palms RV Resort in Yuma where we are staying did the job yesterday. 3:10 Diesel Works is the name. Highly recommended. They knew what they were doing and were ready for us at the appointment time. While waiting for the seal and gaskets to arrive they drained the air tanks (all dry), cleaned the AC evaporator mounted just forward of the drive axle in our coach (very dirty and had not been touched the whole time we have owned the coach), cleaned and and adjusted the brakes, lubed the brake cams, cleaned up the oil mess on the tires and replaced the lube in the differential. Charged three hours labor plus parts and tax for a total of $510.10. We were in at 8:30 and out at 3:30.
Rush Truck Center said they could not do the job until late March, past the time we are scheduled to leave. They are full doing work on the hundreds of trucks associated with the huge ag business here. Most of the leafy veggies consumed in the US come from this area both in the US and in MX.

Thanks for sharing the great news, Jerry! Nice to hear how well they took care of you.
Just curious… how did you find them?

Great to hear!!!!

I found them after Rush said no way to my job within the time frame we had. Internet search brought up 3:10 diesel nearby. Family owned business with the son sitting at the front desk. I drove over to talk to them and he was very reassuring about their ability to do the job right.
