When I apply brakes hard there is a knock which sounds like it is in the drive line. When I start driving from a stop I may also get the same sound. The sound comes from under the floor boards in the front. Also, sometimes when I turn the wheel to the left while in a parking lot I get a similar sound. A mechanic said it was the transfer case/drive line as I have "all wheel drive". Will you please comment? Thank you.
knock in drive line and front end on 2004 Chrysler Pacifica
Start with the basics. Check out all your lower ball joints before you start to condemn a trans. There a lot of AWD vehicles that have ball joints that go bad.
at least one motor mount is broken.
That is what it sounds like when you have a bad cv joint or the whole axle assembly. You can get a newly rebuilt one for $75 dollars from a parts store, but if you don't know how to install it, you can take it to a mechanic, and they will usually charge around $90 or so to fix it.
I was told by an ex-chrylser mechanic that the transmission mounts can go bad on these cars and cause the same problem
I have a 2005 Pacifica I had the same noise was told it was a motor mount I had that fixed and I have not had another problem or noise.
you ever get an answer on the knock issue when you stop and go?
