I run the 4-link AND the panhard bar in a 96. I actually drill some small holes in the rubber of the axles ear bushing before installing them trying to weaken them a bit. The closer I got to running at the front, the faster I started pushing the black rubber out of the axle end housing sleeve. Sometimes they last 4-5 weekends.......sometimes they last 1-2 weekends. I've changed 15-20 of them in 5 years, usually just one at a time (doing both will really tighten up the car!)
