So my driver's side motor mount is shot and I need to replace it. I've been trying to get a game plan together to get in there and get it done. There doesn't appear to be enough room to get it out from underneath due to the front differential. It looks to me that I could remove the exhaust manifold, plugs etc.. and bring it up through that way.
Can anyone shed some light on this that has done it before?
The truck is a 2008 Extended cab Silverado LTZ Z71
