I received my replacement Barker Superjack and I've installed it. Its an exact replacement as the original shipped from Barker via Vintage Trailer Supply. However when there is weight on the jack and lowering it there is a clunking noise as it engages and lowers the tongue. As soon as the weight is off the noise goes away.
I had to rotate the head on the shaft 90 deg to have it clear the propane tank but that is explained in the instructions as normal without having to retime the shaft.
My old jack didn't sound like this when retracting with weight.
Is this common or do I have a defective unit?
