We were about 5 miles from our destination when the TPMS alarm sounded. Rapid pressure lose. Right rear tire flat. No big deal, had room to pull over to put on spare.
Pulled tire off and noticed a deep groove around the rear sidewall of tire. It’s then I discovered the problem. The shackles holding the rear axle leaf springs to the center equalizer had broken. The tire had been rubbing up against the shock absorber bracket.
Since we were so close I put the spare on and we limped the final few miles. It was then I discovered that the shackles on the other side was broken also. So basically the only thing holding the rear axle on was the two rear leaf spring bolts. Can’t say how long it had been this way. Shudder to think what could have happened.
