Hi I have a 2001 cherokee sport 4.0 auto., that I have been working on and have an exhaust question,., From the exhaust manifold to the pipe going towards the rear of the car right by the bell housing thier is a flange their that connects the pipe to the exhaust manifold .. It has a gasket in between the two .. my question is are they studs that connect the two or nuts and bolts they are so rusted that I can not tell ?? One side looks like a very rusted nut the other side is almost impossiable to tell ?? Fortunetly the pipes are in great shape it is just the bolts/ or studs that hold them together that are completely rusted?? If I knew they were nut and bolts I would just saw zall them but not sure .. It is quiet for now but was going to repair it before it breaks?? Any body knows please give me a shout Thanks Bill

 

They are drive studs. O'reiily, advance auto, and maybe even Analzone, have them. Made by Dorman.

Trick is getting them out when the are rusted in place.

 

Ok Thanks was afraid of that no way these are coming out, it almost looks like they were underwater?? but just a really bad rust issue?? Thanks again for the quick reply.. I am wondering if I should just order that pipe from the manifold to the resinator??
