Yours is inside the tranny? I'm pretty sure 93 was the last year they did that on the YJ. That's gotta get expensive. I only say that because mine is getting weak in my 94 and I had to do some research on it.
As far as the part store brands, just get one with a lifetime warranty. I had a ford ranger that dropped one and it lasted me for years until I sold the truck. It was from autozone. I guess its just the luck of the draw.
