No. I have changed both my control arms 2 times already (went the cheap way both times) and installed the existing pin. After all it is a piece of metal (aluminum I think) that can not go bad.

 

I just did my LCAs last weekend. I thought I could do it without buying the "Bush pins" (that's Nissan's label). I could have, but to get the old ones out I ended up bring them to work and using a massive vise and a 3ft pipe wrench plus some good penetrating oil to turn the old sleeve off of the pin. I had already ordered new pins form Nissan (it is a dealer only part). My old ones ended up perfectly serviceable once I got the bushing sleeves off, so I could sell them if anyone is interested. Send me a PM or I'll post them in the classifieds this weekend (if I can, probably don't have enough posts yet.)
