Anybody have a tool or trick for getting the nuts off the turbo studs that mount the turbo to the manifold.? The back one on the bottom is a struggle every time. Just no good access. Even hard to get a torch in there. Unless I'm missing something.

I use a half moon wrench on the nut with a double nut in the other end of the wrench and a short socket hooked to a breaker bar short enough to get into the space below to break the nut loose. Once loose the nuts usually come of by hand.

I’m not sure what kind Of truck your working on . But I use a doubled ended box wrench since there longer. And take off the passenger fender one the m2 trucks, then use a large pry bar on the end of the wrench to break it loose. It takes a bit of work at times to get the correct angle but it’s work on a lot of them for me since once it’s loose I can just a open ended wrench.

Thank you, Will look into a long box end. I see mostly buses. The fenders are a pain to get off. This was suggested by Kevin Looney on IATN, a Miller 9866 wrench. Apparently a Dodge “special” tool. I have one coming. Will update with how it works out. BTW are you a Penske tech?

Ordered and received the wrenches. No turbos at the moment so I can't say for sure they wil work. Other reviews were very positive so we will see.

The 9866 is working out very well.
