Pulley Replacement
Lots of rattling and noise in the engine. I hear this is a common issue with the bearings in the pulleys. Looking to replace but having a hard time finding the parts. Does anyone have the part #'s or have advice on replacing all idler and non idler pulley's. I believe the noise is coming from my power steering pump. Either way I'd like to replace all I currently have 117k miles on the engine. Any advice would be helpful!

Speedriven sells billet aluminum replacements for the two small plastic idlers and is coming out with a replacement for the ribbed idler on the top corner of the V-12 engine. Not sure if any of these fit V-8's but you could call them and ask.

I believe they can or are making it for the V8, the original OEM are made out of plastic and fall apart on people while driving not only leaving them stranded but damaging stuff as well. Don't get the plastic OEM ones contact Marcin at Speedriven he should be able to help you out.
Good Luck
