I just bought this 06 1500 5.7 hemi qc 4x4. trucks got 57000 kms on it. Suspensions stock(far as I can tell), with a levelling kit (I believe 2.5" spacer). When I took the truck for a test drive before I bought it I shifted into 4x4 at around 60kms/h and drove some back roads (snow covered) everything went fine, then i went back into 2wd driving back to the dealer. Truck was fine, i bought it this sat. Today I took posession of it and drove it around town. The roads here are fairly icey so I drove around in 4 high.

This is where I noticed a slight side to side wobble in the rear end while slowly accelerating from a roll of around 20 km/h to 35 km/h. But only while in 4x4 I've noticed it. I'll drive around in 2wd tomorrow and see if it does the same thing. At higher speeds there is no wobble or vibration. Any ideas what causing this?? Shouldnt a wobble get worse at higher speeds?? I dont know much about 4x4s but any help would be much appreciated.

 

I dont know why the rear would be wobbling in 4x4, sometimes mine does this at 45mph and its probably tire balancing issues

 

hmm. maybe. Im just reading through the service manual. What about a sticking inner tripod joint? That might produce a shudder while accelerating at low speeds, But wouldnt it get worse as u get up to highway speeds? On my test drive the truck was perfectly fine at 100-130 km/h.

Man I think I need to get crawl under the truck and familiarise myself with the components.

 

Man I love having a truck. I was able to go underneather the truck without jacking it up. Good luck doing that on a slammed celica, even got to drive up on 2x4s to get clearance to fit the jack. This truck is def refreshing. Although not looking forward to my first of many trips to the gas station. Oh well got to pay to play.

I looked over a bunch of components and I can't find anything obviously wrong.

 

After installing my 2.5" level, I have a "shudder" in 4hi around 30-40mph (which is in your range of 60 kph). It seems to be somewhat common after a level, but I don't know what the fix is (besides removing the level).

Congrats on the truck purchase. I also like being able to get under the truck without jacking it up. I can barely get a jack under my mustang, so it's refreshing to lay on a creeper and roll under the truck.
