I recently ordered a set of Passat B5.5 BHW motor mounts. They arrived yesterday and I installed them tonight.
It was a one hour job. I put the car up on stands, then placed a jack under the oil pan. I then took the nuts off the motor mounts (had to remove the intercooler on one side to access the top side nut. I then removed 6 large bolts holding the left and right brackets bolted to the subframe. These brackets hold the sway bar and pick-up the bottom side of the motor mounts. With these bolts removed it was easy to drop these brackets down, swap in the new motor mounts, and push it back up, being carefull to keep the alignment pins in the right slots.
In comparing the V6 mounts and the BHW mounts, there is a really big stiffness difference. That is the BHW ones are much more pliable.
On testing, I found that chassis vibration is a lot more managable now. My hood lip is no longer forming a standing wave at idle
, my steering wheel is not bouncing all over the place, my dash is not buzzing and my front bumper is not buzzing
I have to conceed that it is still not as good as I want it and will go ahead with the new gear drive balance shaft assembly this summer.
