Every day we read of tire, brake, axle and wheel bearing problems on these forums. I wonder how many of these problems are caused by "mechanics" that perform annual safety inspections.
I have had so many problems with these inspections that I refused to have my trailer inspected for the last two years. Now PA has stepped up enforcement on the PA turnpike with an officer doing nothing all day long but look for stickers.
So I take my trailer to a local inspection station. The "mechanic" rolls out the largest floor jack that I have ever seen. I told him that he is not to use it because he can't jack anywhere near the wheel. He says "You don't like it when someone tells you how to do your job, the state tells me how to do mine, now just how do you want it jacked?" I told him that I don't want him to jack it and left.
If I would not have been there watching this monkey, he likely would have bent both axles.
YOU are wrong.
The jack CAN be placed anywhere EXCEPT the MIDDLE of the axle tube (the middle of the axle tube is the weakest point and has an intentional "bow" or "camber" built in, jacking here can bend or damage the tube).
I am not sure as to how you PLAN to change tires or inspect the brakes without JACKING UP the axle.
The best place for the jack is DIRECTLY UNDER the AXLE where the AXLE IS BOLTED TO the springs. This places the LEAST amount of stress on the axle and suspension.
Alternately if that can not be done then jack under the spring as close as possible to the AXLE.
Do not jack on the spring mounts or the equalizer.
If you are jacking on the FRAME of the trailer you ARE risking DAMAGING THE FRAME. The reason for this is you have to jack the frame considerably MORE to unload the springs in order to get the wheel off the ground. In effect you are TWISTING the frame to make that happen.
The inspection mechanic WAS doing it right in fact my mechanic has used a semi truck lift to lift the entire trailer off all four wheels at the same time. Placed the jack pads exactly under the point where the axle tubes are connected to the springs.
Believe it or not most PA inspection mechanics DO "know their stuff", I have only run into a couple of mechanics over the years that actually didn't have a clue.
Take it back and get it inspected...
On edit, the only other exception would be if you have TORSION suspension, on that type you are to place the jack BESIDE the tube basically on the frame. This will jack the entire frame up but places less stress on the frame. Jacking on a torsion axle can damage it.
It's great that you can say that I am wrong without even trying to comprehend what I wrote.
1. The jack was TOO WIDE so that there was no way to jack the axle under, or near, the spring.
2. The "mechanic" would not listen to a word I said.
3. I did not ask for advice on how to jack a trailer.
4. I replaced the axles myself when the trailer was new because they were already bent. I don't plan on doing it again.
5. I provided a jack point when I made the shock mounts that are on the trailer.
I call B.S.
1) axle tubes are NOT PAPER THIN and WILL "support" full weight at least 6"-12" inboard. If they couldn't support this weight on the inboard side what makes you think that they can support all the weight ON THE TIRE SIDE.
2) Mechanic IS trained and IS following procedures, in fact SAFE procedures for not only your trailer but the MECHANIC as well.
3) YOU can jack the trailer any way you want, heck perhaps a forklift or crane would "meet" your "standards" but for many other folks it seems to be more normal not to sweat it as long as the jacking is not in the middle of the axle tube.
4) The axles HAVE a natural "bend" in them, this "bend" is to provide the PROPER camber of the tires while under max loading conditions. Many people "mistake" this "bend" as if there is something wrong with the axles when there is nothing wrong with the axles.
5) If I was the mechanic I PERSONALLY WOULD NOT "TRUST" someones "back yard" mechanics jerry rig "jacking point" and therefore the mechanic was totally correct to not use you homemade part.
As far as what Dexter has to say, if you READ THE ENTIRE PDF they state that THEY (Dexter) can not guarantee the spring mounts nor any other suspension parts quality or strength. THAT IS WHY THEY MENTION JACKING ON THE TRAILER FRAME.
My suggestion is you find another shop, THERE ARE LOTS of them or perhaps since you feel your "quality and standards" are above all inspection mechanics that YOU should go and study and take the inspection course and test. Once you do that YOU CAN INSPECT YOUR OWN vehicles and trailer.
By the way, just because YOU don't like the inspection process it doesn't mean you are above the law. Get it inspected or perhaps move out of state, Ohio doesn't require inspections and often you can see right through their vehicles in places where there is no glass...
