Hello and thanks for using Just Answer. You have started off right by replacing the two mounts that are the usual cause for this. Have you checked the trans mount aswell? I have seen this one to be an issue as well. And does the engine move alot if you hold the brake and press the gas to see the engine torque forwards or back?
If you are turning the wheels, there will be some play in them before the cv joints catch up as well as the diff in the transmission. But Id say there shouldnt be more than a couple of inches of turn before you feel resistance from the transmission.
engine doesn't move by much
More than 2 "
maybe just one
it doesn't rock back and forth
Ok, has the vehicle been in any kind of accident that you know of. I know that these are very finnecky and prone to vibrations if any of the body clip in the front is off at all
i bought the car from someone who bought it used from a dealer
Soooooo not sure then huh?
i noticed some screws are not the same on the air filter housing
the radiator has lots of play
the paint doesn't look original
so i assume work was done to it
maybe was rebuilt
That could be a good determination that some things have been repaired. Since the issue you are saying is occurring in park and neutral the most the things that it most leads to be would be first mounts ( which you have replaced and seemed to rule out), an inner trans issue, which is not usual for this or misaligned body work in the front clip.
he best bet would be to take it to a good body shop to see if they are able to do anything with the chassis bender for your front end to get it better in line to get rid of the vibration and ask them if it looks absolutely obvious to be out of whack.
when i bought the car i drove the car back home assuming i just needed to replace motor mounts
it drove like a normal car would
but the vibration was there the whole time
was felt stronger when accelerating from a stop
and that seems more like a bent frame more than a trans issue.
You did what I would have done first in replacing the mounts.
i had the car up on jack stands
i put it in drive and reverse
and the vibration was pretty much the same
does that rule out a suspension problem?
I would check to see if any hard lines such as ac or power steering arent vibrating on the frame or inner fenders as well.
Be sure to check all hard plastic lines as well.
