I think I have an issue with the right rear axel on my trailer for a 2013 P2. I was doing some maintanance and noticed there was some excessive play in the wheel. Thinking I had a Vault hub issue, removed the wheel and found the play was at the torsion bar where it is attached to the splined axel. Can this be resolved by tightening the bolt on the torsion bar?The only thing I noticed on the vault hub was the Cap was slightly recessed into the hub, possibly indicating it needs to have some lubrication added. The front wheel cap was approximately 1/16” past, as stated in the Manuel.Any help would be appreciated. Thx
