Axleback/Muffler Removal?

2string1 · 04-17-2021, 01:14 PM

I started to remove the muffler and attempted to remove the nuts. They didn't want to move so I stop for fear of breaking the studs. Do these studs pop out after taking the nuts off?

If they are studs. They don't come out.

The studs are welded on.

Get a small wire brush (powered, if possible) and clean the stud threads that are exposed.
Spray nuts with penetrating oil - PB Blaster, WD-40, etc. Let sit overnight. If rust/corrosion is really bad, repeat.
You're going to need a lot of torque and/or impact. You can buy small electric/battery impacts for pretty cheap nowadays - can be well worth the cost just in reduced frustration levels.

Or use a long-handled wrench.
Applying heat can help but do NOT use an open flame under your car. Even a hair dryer can ignite gas fumes.

Good luck.

Edit: Forget the impact wrench. See discussion below.

You take all the fun out of things. Sometimes, the flame wrench is the only way to go.

Impact gun, no-no on exhaust. Kiss an O2 sensor or 2 good-bye.

You're correct, sir. Thanks for pointing that out.
I'm still working on 60s muscle cars.

Got them off. Just use a regular socket wrench. I was just worried about snapping the studs.
