Not sure if this is the best place to post and ask this but maybe someone out there with more experience can shed light on a problem that I am having with a couple of socket wrenches that I own. Back in the early 90s I replaced my SK socket set (stolen out of the back of my FJ40) with a large set of Craftsman USA sockets including 1/4", 3/8" and 1/2" sockets and wrenches. They've gotten a fair amount of use in the last 25 years or so, but I do my best to take care of my tools. Recently, the 3/8" socket wrench has been slipping and the 1/2" wrench will lock up on occasion. It's annoying and dangerous. I decided to disassemble the 3/8". Nothing really amiss, everything was intact including the ball and spring. There were some fragments, like spinters of metal from the actual gear mechanism but it didn't look that bad. Regardless, I did a full cleaning, WD40 and reassembly. It works without slipping now, but I find (like before) that if you inadvertently nudge the lever (plastic?), it will slip. The lever is wobbly on all three wrenches and the gears on the 3/8" and 1/2" are rough (1/4" is fine). Am I doing something wrong or was Craftsman junk even in the early 90's ? I'm not looking for an excuse to replace them because I like to get the most out of anything I buy, but now I dread having to do maintenance or repair stuff.
