You either need a very long breaker bar or a very strong air impact wrench. Those bolt are put on with a lot of torque. They ususally put locktite on the threads as well.

I usually end up with a 2' long pipe on my breaker bar. Just make sure the T55 Torx is not rounded off and is seated all the way in the bolt head, I tap it in with a hammer to be sure.

As trouttrooper said, they are put on with Loctite. Torch a little heat to them to loosen the Loctite (watch your brake lines), and it should make it easier.

I have an 06 1500 wt 4.8 2wd. My bracket bolts are m14 (14 mm) in diam and 35 mm long not counting the head. They are 10-9 grade so dont expect to find them @ a local retail store. I ordered my from the dealer a week ago and still not here. I believe the head takes an 18 mm socket. Dont try to use 3/8 wrench. Use 1/2 inch breaker bar.
