If u mean the flex joints, there are different part #s depending on the arms, and location. Best bet is call tf and they will send u the right ones. I bought mine through Northridge, but they were shipped right from tf.
Oh, and be prepared to do them again down the road, maybe two times.
Make sure the snap ring is all the way in the grove all the way around. Trust me.
I keep getting dw dry rot or not
Those ones for the upper arms in the axle housing u can get from quadratec for 15$ a piece. I changed mine recently. Used an air hammer and popped em right out. Crown is the maker, and I can get u the part # later if needed.
I don't think the stock arm bushings can be changed...
Can I get the part number?
Ohhhhhhh ok how can I tell my ball joints are bad
