Well, my old Sears jack has seen better days. It's not even a craftsman. Just "sears". It still pumps but when I try to lower it it suddenly releases and the load comes down fairly fast. It is not anywhere the controlled lowering I would like to have. I don't think I can rebuild it, but I might be able to but I don't know if it is even worth it. I've looked at NAPA, O'Rileys, and at the Harbor Freight ad. I know HF has some real spiffy aluminum jacks and they come with 4 and 5 star ratings. But I'm not convinced of the quality when it has a ton of weight on it. Not doing it for a job, just working on cars and jeeps. Don't need a real spendy jack. So, what do you guys recommend?
