Replacing Trailer Wheel Seals

Determining if I want to go through the process if I want to do the work myself or someone else. I'm asking this as I have an estimate of around $2000 to replace wheel seals and s-cam bushings. The big part is removing the wheel assembly, once that is off, I believe replacing the bushings would be fairly simple - maybe not.

Looking for responses that may decide if I do it myself or have a shop do it. I am mechanically knowledgeable.

S-Cams were new a couple of years ago. Brakes are also new. Wheels have outboard drums. Drums and shoes are in great shape.

You may ask why the bushings failed - evidently there is a grease zert on the bushings that need to be greased. Petro Lube obviously missed those grease zerts - even though the trailer has been greased on a religious basis.

Are you replacing the brake shoes also? Next question are the wheels outboard brake drums or not. The outboard brake drums come off after the rims, and lake the hub assembly much easier to work with. When you replace the s-cam bushings, usually the s-cams get replaced also, AND do you know when a brake drum is worn past being used again? Just by the way you asked the question, I would recommend a mechanic do it for you, watch and learn, buy some of the tools and do it yourself next time.

2000.00 seems a little high. TA-Petro have a special on brake replacement about 250 an axle. Try a TA Petro near a large city so they can get the parts, or get the parts and bring them with you. Perhaps you could negotiate a bit since they didn't grease the s-cams.

I think $2,000 is a fairly average price to change all the s-cam bushings. The wheel seals are just part of the job, so not sure why you titled your post the way you did.

After re-reading your post, it sounds as if you are asking if changing the wheel seals if difficult. I would say no,it is not difficult, if you have the right tools.

You never said if this is a truck or trailer your working on. Wheel seals are not that bad to put in like interstate5trucker the tools is the key seal driver if you don't have one is about 100 dollars. Depending on the type of S-Cam bushings aren't that bad as long as you have drift to knock the old ones out. Now if the bushings are on a trailer you could ones that drive in or bolt in. Any way you do it 2000 dollars is a lot of money for just S-Cam bushings and wheels. I just did all S-Cam bushings and wheel seals on the truck and cost was 130 dollars for 4 wheel seals and S-Cam bushings was about 60 Dollars for all 4 wheels.
