Acceleration and Vibration

okay question, has anyone else had problems in acceleration? I have a 2005 4.0L and depending on when I choose to accelerate, its almost like the transmition is slipping. I have about 71K on the truck, this only happens when i'm trying to accelerate, lets say from a more moderate speed to pass someone or merge onto the highway.

2nd question I have is realitive to the front end. there is a lot of vibration from the frt of the truck, i can get an alignment, but with in a few months the issue is back. Anyone have any ideas?

 

Do you have a lift on it?

 

nope no lift...i haven't been able to do anything to it yet. kinda sad really...

 

Hmm.... I have no clue then. When I added a 3" lift, I got driveline vibration and put in a 1/4" Carrier Bearing Drop (which lessened the angle of the driveshaft) and thus, ending the vibrations.

When is the last time the wheels themselves were balanced?

You could have the transmission fluid changed. It is a sealed tranny, so you'll likely have to have a dealer or other shop do it. You are supposed to have it changed at 100k miles anyway - so it couldn't really hurt. That might help some.

 

Your tires could be shit for done or just out of balance, get a road force balance and see if it goes away. How many miles on what kind of tire you got? I got same vibs plus in the whole body of the truck and its cause my m/t tires are gone
