Hey guys iv tried this already in the suspension forum but only got one response im changing the front driver side ball joints with spicer units on my 06 and discovered my lower ball joint was splined. Now the question i have is do i have to stay with splined because i have smooth replacements. I can slide it in 3/4 of the way by hand and the last 1/4 will have to be pressed to get the snap ring on. Can i still make this work or do i have to get a new splined lower?? i just read spicer ball joints are flared slightly on top which i think is why ill have to finish with the press i just dont want to mess it up and have it become a safety issue. I did read that you can use a chisel and make little dimples to make it more snug. The joint is very snug when it gets up higher and does not rotate at all. Or should i say it and get a napa splined which is 5 mins from my house??
