Okay new to the site but didn't see anything like this when I was searching. I purchased a 06 2500 4 door, 4wd, st trim package. The previous owner had pulled the engine and a shop fire destroyed the engine parts so he sold the truck to me. I purchased a engine from a running, driving truck and had it delivered. The truck the engine came out of was a 2006 2500 reg. cab, 2wd and both have automatic trans. The problem I am having on the install, first time on a Dodge done quite a few over the years in other cars and trucks, so anyway I have the engine in the compartment and bolted to the trans. When I set the drivers side motor mount in the bolt cradle on the frame it lines up fine, however when I switch to the passenger side the engine needs to be tilted a few degrees down and towards the passenger side making the engine sit nose down a few degrees and the front is shifted to the pass. side a few degrees. WEIRD! The engine I got was a complete takeout and still had the engine mount brackets attached when I received it. I have no idea why this tilt and lean is happening and have double checked everything about 10 times. I researched to make sure the mount brackets that came on the engine are correct and the seem to be by the part numbers. Any ideas?

thanks

 

Someone correct me if I am wrong, but I was told there is a difference between 2wd and 4wd engines. Not as far as the block but some of the other parts including the engine controller.
When I was looking at a motor from a bone yard vs. a rebuild they said you can't drop a 2wd into a 4wd truck.

 

Okay should have posted an update. After calling about 8 dealerships getting the same answer from all of them I double checked the part numbers they were giving me to what I have with the engine. Turns out that in 06 there is a different engine mount bracket for 2wd and 4wd. I had the 52021135aa on the engine and it calls for the 52021137aa. I called a few of the dealers back and they still argued with me that the bracket I have doesn't exist. Kinda funny. And with my luck the part I need is on back order with no shipping date listed. Thanks for your help.

 

ebay or amazon. that's my suggestion
