Motor mount questions - 92 Regal

I'm almost sure this is where I'm at now...the need to finally replace the powertrain mounts up front, after over a quarter of a million miles on my 92 Regal. One way I can tell is that, when you tap on the accelerator very quickly, there is a subtle "movement" that comes through the suspension/steering wheel... that wasn't there before. In an earlier Buick my Dad owned, this same thing was present and it was the motor mounts.

 

On these Regals with the 3800 V6, how many engine and transaxle mounts are there? Roughly, where are they located?

 

I will NOT be doing this. I will be taking it in. I don't have the set up to do this and I only do the simplest of repairs on my own. Therefore, what do they generally charge for the parts and the labor?

worn control arm bushings might also contribute to the feeling in the suspension that you get

Here's another thing I forgot to mention. In 30,000 miles that the last set of tires have been on this car, there has been NO abnormal wear. Also, at higher speeds, there is a vibration/shimmy that is only felt depending on the position of the steering wheel and a minor adjustment of the steering wheel "clears it"

 

I'm thinking bushings and tie rods are not the culprits. Tie rods were replaced last year, as was the dogbone. Can bushings on W-bodies be tested for whether they are still up to par? I've been told repeatedly at Big O, Goodyear and such places, when I'm in for oil changes, that everything in my lower suspension looks great.

The most obvious motor mount fail is a non-subtle "thump" when you hit the accelerator from a dead stop.

 

To have it done at a local shop...not a chain...I remember paying about 250.00 a few years ago on my '89. I suspect you'd be looking at around 300 depending on where you live.

Yes, what I was thinking, after over 250,000 original miles.

 

How many mounts (engine and transaxle) are there total for the 3800 V6 and 4-speed transaxle.

There are two lower engine mounts(one in front, one in rear, located on the left side of the engine if you're facing the front of the car), one transaxle mount, and then the dogbone mount on top of the engine.

Awesome. Thanks. That makes sense for the symmetrical weight of the engine and the narrowed area required for the transaxle. The dogbone has been replaced.
