DIY vs. "professional" maintenance

Took our 26' tow-behind to a local brake shop after reading advice on wheel bearing lubrication and deciding I didn't have the tools & talent. Watching "professional" perform jacking, hub-removal and reinstallation I noticed three things: 1. jack placed under axle; 2. spindle not wiped clean before replacing hubs; and 3. new seals not used (according to bill). Each item contradicted tutorials I'd read or viewed leaving me to wonder if I shouldn't have attempted the work myself. Would any of the three "mistakes" constitute a serious offense?

Back in the old days my boss would always insist on replacing the seals.
Inspect and replace was fine but money is made on replacement so we did it.

Same goes for 'transmission filters'... never saw a dirty filter but we always replaced it because the customer expected it and we made money on the parts. It is really just a strainer.

Thanks for not "hounding the mechanic". I've worked in a few shops, everything from Lamborghini to lawn mowers and there is hardly anything worse than a customer standing over your shoulder, in most cases. About the only thing worse is a customer advising how to accomplish the task.

For all of the mechanic bashers out there, the shop calls most of the shots, not the guy with wrench in hand. If you have an issue with how the work is performed, it's best to relate this to the service writer or management. The word will be passed downhill.

Without knowing the condition of the trailer axles, the process guidelines of the shop, or the customer's input for the task, it's difficult to pass judgement on the maintenance performed. If the seals weren't leaking before the work was started, a decision might have been made to reuse the existing seals. If inspection shows that the inner bearing is good, new grease can be forced into the bearing, ala--ship-in-a-bottle. This saves money for the customer and time for the shop. Since most of the force on the bearings rides on the outer bearing, I've done this many times myself. I've never had an inner bearing fail from this process.

I'd suggest that the OP have the work done, next time, by a different shop or DIY.

Earning a 10 hr per-day check in a 8 hr day is something a mechanic is forced to learn how to do. We all want to earn more, don't we? Of course, a good mechanic does it right (no comebacks).
Personally, I enjoy the hobby element of doing my own maintenance and repairs. Besides, I've got more time than money (right now).

There is nothing wrong w/ jacking under the axle when staying against the U Bolts,.....don't matter what any book says,....we do use common sense.
The rest is penny anny stuff. If you think you will find a shop to do everything perfect, go for it. In reality, you won't. So if you don't like what you see, either stay out of the shop, or do it yourself.

Great question, that would be done by a mechanic whose hobby is building a ship in a bottle. :B

There are excellent mechanics out there, lots of them. The problem is finding them and in a shop environment they may be under a lot of pressure from management to git'er done & move on to the next job which pays the bills. I have the luxury of time & can spend an hour wandering around under a vehicle for an hour looking for a project. At the going labor rates, I don't want them doing that.

If I were writing a DIY turtorial I would likely recommend replacement of seals and such only because of the cost/risk factor

Cost me noting to suggest you replace them v/s the risk of failure and law suit.

But if I were DOING the job myself...I might not replace them because the cost is no longer zero.

As this was my first attempt, I have a lot to learn about using this "forum." Thanks for the replies. Regarding the question of a torque wrench, all I observed was the pneumatic gun. (Can't miss that sound!) Spindle nut adjustment technique wasn't witnessed either. I was reluctant to hover over the mechanic even though work was done outside the shop.

Thanks again.

If you must have it done, take it toreputable trailer shop next time. Not a brake shop. A brake and/or auto shop these days isn't dealing with bearings on most cars like years ago. Bearings are sealed in hub assemblies, and that's what they are used to working on. It's very likely this character has never done real bearings before.

And a good trailer shop knows exactly where to jack up the trailer.


I agree with the above. Also the fact that many shops that just do brakes may have entry level technicians who are not used to doing things the "old school" way like an experienced trailer tech.
