First let me send a special thanks to OldCoot for making me aware of a design flaw in the mounts of our axels. I was digging through some old threads yesterday and found the flaw that OC has mentioned many times. The picture below should explain everything, that space should not be there, the mounts are moving. I will loosen the bolts holding the mounts, use my 6 ton bottle jack to move the mounts back into place and torque the bolts back to specs. Drill 1/2" holes through the 2"X 6" frame above the bracket and bolt it into place with gr 8 1/2" X 1 1/4" bolts, washers, lock nuts and torque them down as per O.C. 4 times on each axel. The front axels have the gaps towards the front of the RV, the rear axels have the gaps towards the back. I was wondering why I was having to close up my X chocks little by little, now I know. These are Dexter axels with about 4,000 miles on them.
