I am looking to tackle replacing the left side Exhaust studs.

[98EXPY 5-0]

Last night I removed the fender liner on the driver's side to prepare to replace the Exhaust Manifold studs.

Wow, these things look difficult to get to. I can't even see the bottom ones through the wheel well. At this point, to avoid breaking anything off, I would love to be able to just cut the nuts off and leave the whole stud behind. Most of the nuts look so rusted they are round.

I also don't see how to get at the one in front behind the master cylinder.


I also want to replace the studs and nuts that bolt the manifold to the Y pipe. Is it a stud with a nut on each end? Again, lots of rust, so it's hard to tell.


I was quoted $650 at a dealer, and the parts are like $50. With that much difference, I really don't want to pay that much to have it done.

I sprayed penetrating oil on them last night. I'll do it again tonight.

Any advice? I haven't been able to find much info online about guys doing this repair themselves.

Any recomended "specialty" tools?

One of the mechanics pulled one they did a couple months ago. It was quoted as 6 hours, studs, nuts, y-pipe studs and nuts, gaskets all for one side.

If ever there was a job worth $650.......this one is it.
I've never changed them on an expedition but I have on a '99 f-250 (more room) and its no fun.

Well I need the Expedition for work, and I can't afford to pay to have it done. So I guess I'm moving forward with it.

It can be done.....just give yourself a full weekend to do it in case you run into any issues.

.........and there will be issues. Bet on it.

If you're done with it, please let us know how it turned out.

A buddy of mine has a lift in his garage and every mechanics tool imaginable. He asked me why I wasn't driving it and I told him about the exhaust manifold. He said he's done it 4 or 5 times and would basically do it for me at his place if I play gopher. I am waiting until he gets another car off of the lift in a week or so.

I'll report back.


I have been spraying penetrating oil on the studs every couple days. I started with Liquid Wrench brand, but I have now switched to PB Blaster. I started it up the other day. After a couple minutes, there was smoke pouring from the manifold.

Nice.....someone who has done it before is a bonus.
especially someone with a lift.
