They'll pop and carry on during slow speed turns on pavement, but I've never had a problem with one, and I've put them to some hard core use over the years. But yeah, a part-time locker would be better for a daily driver.
I was 5? years into my Land Cruiser journey before I first owned a locking differential (ARB's, still have them in the same FJ40 22 years later) BUT had I know how inexpensive Lock-Rights were and how easy they could be installed, I would have rocked them F/R in my FJ40 right off the bat. Tires chirping in a parking lot? Awesome for a 16 year old
