After I discovered my Titan squeaked like crazy when I drove down the road when I had the back window down, I discovered the CHEAP imitation plastic boots over the Rancho shocks were rubbing against the shock itself causing the squeaking. I noticed the front shocks had the real rubber boots on them like they should, so I bought two new red rubber boots and replaced the two rear fake plastic boots. Took me about an hour to do, all in all, pretty easy to do. My suspension is now squeek free and looks a lot better too now that those cheap boots are off. :cheers: Plus the rubber boots function a lot better. Why did Nissan put these fake plastic boots on in the first place??? :crying: The rubber boots cost me 5 bucks for both of them!
