If anyone is interested: I know whiteline discontinued these, but there are still some available. I had the same problem with my kit. After being installed for around 6 months, one of the ball joint boots was torn, and the other, as well as the two tie rod ends were about to tear. In Oder to get them replaced, or get my money back, I was going to have to pull them all off, send them back, wait for a determination, and then get a replacement set or a credit. Meanwhile, put stock stuff back on and pay for re-alignment. No thanks. I found this website
http://dustboots.eu/catalogs/ball-jo...boots-size.htm. When I measured the stock boots from my Oem parts, then found the closest fit on that website, it took me to an eBay vendor. I ordered these two:

http://www.ebay.com/itm/161802538801...%3AMEBIDX%3AIT. I have them on now, they are polyurethane, and much tougher than the whiteline dustboots. They are slightly larger, which is what I believe was the problem with whiteline ball joint boots- too small. There was zero contamination in the one with the torn boot, as I believe I caught it in time. Anyway, buys me some time to get some better roll center ball joints. BTW, I love the whole of all my suspension mods. These fixed the vagueness I felt in the steering when I lowered my car.
