I bought a set of the Hydraulic car dolly and wheel lift Go-Cart vehicle positioning jacks While the jack units seem to be good quality, the casters are ****. I complained and sent pictures of my micrometer detailed measurements of the problem with the wheels . This is when the parade started. Bendpak started to send casters and eventually a new set of Go-Cart jacks. The parade of stuff continued until I called and said, "Enough already."
The replacement casters were much better but the quality was still sloppy. The casters would flop over and jam. The bearings are bad. The roller bearings are side-cutter chopped lengths of soft wire.
Now, I have all of this stuff and still nothing that works like it should. One of the jacks came without a check ball so it will never work.
This **** is expensive, in Canada. I am out of pocket about $800. I could have done as well for much less $$ at KMS or Princess Auto.
I have not decided what to do with this ****. I cannot give it away and tossing it all in the recycling is not an option, just yet.
I am in the market for a four post lift. I have options that may not include BP.
