Interesting development regarding PDI - U-bolts

I cannot remember if George posted about this or not, but even if so, it bears repeating. George is who clued me and the dealership in on this and it needs added to all PDI inspections. Both of our rigs were checked for the proper torque settings on the suspension u-bolts. Amazingly, both of our rigs checked out exactly the same, and it is disturbing to say the least. Of the eight u-bolts, seven did not meet the 60 pound torque requirements. Both rigs, seven out of eight u-bolts were not torqued properly. I also had the torque on the lug nuts checked as well, and there were again a few that had to be tightened down. I watched the service tech check the u-bolts, and was totally amazed when several had to be turned more than a half turn to meet torque specs. The dealership has informed us that the u-bolt torque will be checked on all subsequent orders. I know it is a pain, but as previously reported many, many times on this forum, everyone needs to check these bolts. They are one of the most critical areas on your rig!!!

Same here on the U bolt torque on our 2013 Big Sky. Nothing has changed...

Several years ago at the Rally I brought up the U bolt question. We were told they were all correct from the factory so I asked for hands on how many had to tighten them and almost everyone in the room raised their hands (the others probably went back to their rigs to check them). Seems like they should have learned something from that.

Ok now another thing for me to worry about! What's a U bolt? How do I ask for them to be checked? Do I say " btw I have concerns "U bolts" are not tight? No joke remember I am not a gear head! Thanks oh and be easy on me, I am like the "Leg Lamp box" in "A Christmas Story". Fragiley?

They are the u-shaped bolts that attach the suspension system to the axles. If you look under your rig, you will see eight sets, two on each end of each axle. The u-bolts will be facing up with the nuts to be checked on top of the axles. (Thanks Carl)

Please report your findings back, I have a hunch they will need tightened.

Uh, don't the U bolts point up with the nuts on top of the spring plates???

Yes, mine have the nuts on top of the spring plates. When I checked mine back in May when we bought it, most every one were not @ 60 lbs.

You are absolutely correct Carl, the U-Bolts are indeed facing up with the nuts on top of the plate. This configuration is called "over slung" meaning the springs are over the axles.

It is also important to know what the torque should be and to not over tighten the bolts. Ours are 1/2" U bolts and should be torqued to a minimum of 45 lbs and a maximum of 70 lbs as per Dexter Axle's Operation Maintenance Service Manual, page 53.

http://www.united-trailers.com/Uploa...s/Manual_6.pdf

Do not assume the dealer will know what the torque should be, heck most of the time they are shipped with improper torque, and Keystone sure does not check them.

Carl is correct, I looked on the MorRyde website and saw this diagram:

Re System

And then looked back at my pictures of the X-Factor install for the 3750 and they indeed are reversed.

Sorry for the misinformation that I will correct.

That link shows and under slung configuration as you described in your previous post Bingo, that is "not" what is on the Montana from the factory as far as spring location.

Page 52 in the link I suggested shows the way they are hung. I am not suggesting we have the "slipper springs" only that they are "over slung".

The springs and axles come as an assembly from Dexter. Keystone attaches the assembly to the frame. Raise hell with Dexter, not Keystone. When I found mine loose, I called Keystone and was set straight on who the culprit was.

One of mine was torqued properly. All others were at least a turn loose. 2 were little more than finger tight.

My U-bolts face up and are torqued to 65 lbs. After the first time torquing them a subsequent check showed they are still holding the torque. From this I find it hard to believe they are torqued at the factory. Or else the transporter is way rough on the trailers and these are coming loose real bad.

Bingo, the diagram shows the u-bolts pointing down because the spring pack is UNDER the axle. My rig is different and the spring packs are on top of the axles and hence the U-bolts point up. The method on my rig raises the trailer so it sits higher in the air. This is known as "reversing the axle" or something like that for rigs that sit too low and don't have enough clearance with the truck bed. Many fifth wheel rigs I've seen these days have the leaf spring packs on top of the axle for height reasons.

Whatever the case, u-bolts up or down, check the torque just to be safe.

Artemus Gordon, when your minions get around to checking this out let us know. I can post a picture if it would help. If I recall, all but two of the eight nuts on my U-bolts were at the proper torque and a couple were WAY off. Now, there have been no problems since (I check every couple of years and am due to do so before my next trip).

The good thing about it is once you torque them properly, you should never have to do it again. If want to go the super safety route, you could loctite them or add another nut (referred to as a jam nut). If you're super paranoid, do both!

Checked ours before our trip to Banff in August. Mind you, this was after six trips prior but not as many miles.

Only two of the 16 were at 65lds. Some were a half turn but several were over a full turn!!

Glad I saw this in a previous post but geez, this is scary.

Tom S, your response keywords are "never should". That's mostly true, but I still check torque for the tires before starting a new trip and during the trip too, (at least every morning right before getting on the road). I do recheck the torque and while I agree they should be tight and correct, one must check in order to confirm. At the very best you should find the torque is fine and that the click is quick (for the clicker type of wrench - I have two) without the feeling of reseating the nut. I don't feel the need to mess with loctite or jam nuts. That would just make it harder to check the torque when the time comes. I also don't find a need to check every single nut and bolt on my TV or RV. I'll stick with the ones that could be problematic (ubolts and wheel lugs).

Oops, and there are 16 nuts to check, not 8. It's 8 per axle.

Thanks guys for the reminder on this. Since getting our new rig I completely forgot to do this. Guess I now have a job to do next day off!!

We asked our dealer to check the u bolts but he did not so when I checked them we found the same thing. Two were tight and the rest were loose. Two were very loose. At the fall rally I addressed this with the service center, the fifteen minute tech and one of the engineers at the factory tour. They all said they would make an issue of it and get it corrected. Must of fell on deaf ears.
