Wheel Torque Surprise!

We were just getting ready to leave Dallas and travel to South Carolina to visit friends. As I normally do before hitting the road for a long trip, I check the wheel lugs for proper torque. When I checked the torque on the first wheel...the entire axle moved! The main spring that connects to to frame was completely broken in two...the rear of the spring was the only thing holding the axle on! How thankful I was for checking the wheels before departure. To add to the seriousness of the issue, the rear axle had a broken spring also, I'm sure from having to take on the additional weigh.

I couldn't find anyone who stocked the spring sets, but managed to find a spring shop in Ft Worth that custom made me two sets. I finished the install today, and we plan to leave for South Carolina tomorrow.

We have never over loaded our rig; however, over the last three years of full-timing, we have traveled on some terrible roads. I guess a "spring check" will now be a part of the departure checklist!

Glad you caught it in time. It could have been ugly

How did you get the weight off of the axles to change the springs?

Our site was on a slight incline, and low on the side of the broken springs. The Level Up system took a lot of pressure off the axles. I blocked the frame in case of hydraulic failure, then used two axle jacks for adjusting the axles/springs for alignment. It really went pretty smoothly after I completed the first axle...I discovered there is a sequence you need to follow in order for everything to line up properly.

Grizzby can you tell me the easy way of doing it. I need to remove my shackles so as to drill holes in the frame to mount my joy rider shocks?

I can only speak from my recent experience...some on the forum have already completed a shock install and may be a better source on specfic steps.

If it's just the shackles you need to remove, these are the steps I would take:

1. Raise the coach with the Level Up sys and place jack stands under the frame.

2. Use an axle jack to remove the wheel, and to take weigh off the axle.

3. Remove the bolts from the shackle and then lower the axle using the axle jack.

I'm not familiar with the shock installation process. However, I learned from my spring repair, the last thing you do is tighten up the u-bolts that hold the springs and axles together. With them loose, it allows for spring/axle movement for aligning the bolt holes.

I hope this helps. Again you might want to ask forum members who have actually completed a shock set install. Feel free to call me if you'd like.

Does anyone know the actual torque spec for the lug nuts on the 8k axles?

Here is a link for Lipperts 8k axles.

https://www.lci1.com/assets/content/...ers-Manual.pdf

This covers them from 8K to 12K. On page 17 of the pdf it shows this chart.

Thanks very much!

Wow I have the 8k with 17.5's. It shows 190-210 foot lbs. That is way more torque than I would have guessed.
