cannot turn the muffler for rear wheel removal

Post by tprender » Mon Jan 09, 2017 2:44 pm



I was checking on the splines on my 1500 a few weeks ago and I could not get the mufflers to turn for getting the axle out. I was able to get the axle out by taking off the shocks and raising the wheel above the muffler. I did spray PB blaster and let it soak over night and tried hitting with my dead blow hammer, but the neither muffler would move. (Yes i did loosen up the clamps.) Is there some trick to get the mufflers to turn. I guess that they are rusted on pretty good. Asking, because I will be needing to put a new rear tire on around the end of May. Put the old tire back on, I think that it has about 3000-5000 miles left of wear.

I use a strap wrench, like this:

The problem with pushing the mufflers down is that it puts a tremendous amount of leverage at the collector (where the muffler fastens to). Basically to move the muffler down, you are rotating it on the collector outlet. I put the strap wrench on the muffler as close to the front end of it as possible, then use it to apply rotational force, sometimes while also giving a few glancing blows around the outlet area with a rubber mallet or nylon dead blow hammer. I have yet to have one not come loose this way, and the collector remains intact and undamaged.

I will however soak it thoroughly with PB Blaster for a day or two in advance.

I have done the same thing with good results. It helps to have someone on the end of the muffler applying rotational force as well with their hands. Soaking the muffler gasket at the collector with PB Blaster or equivalent for a couple of days is the only way to get things loosened up. Be patient and persistent. It will work for you.

I was using a strap wrench also, and it did not help.

I never rotate the mufflers, I remove the shocks and raise the wheel method , never have to worry about buggering up my exhaust seals that way. 8-)

I always rotate the mufflers or remove them. I'm guessing you unbolted the bolt towards the rear of the muffler under the were the saddle bag would be? Two 12mm wrenches. I take ahold of the rear end of the muffler and push and pull and up and down a few times to loosen the clamps at the collector and rotate it at the same time.

That will NEVER loosen mine. I have to rotate it (after freeing with PB Blaster) right at the collector with the strap wrench (after loosening the clamp of course). Mine are on there quite tight.
