picture is too dark, I can't see it well enough to identify it.

What year model car do you have, again?

That is the original differential mount. It has rubber vulcanized to it to isolate vibration and hold the differential down when accelerating. If you suspect the rubber has separated from the metal, use a big pry bar and check for excessive play. You should see the rubber flexing when you pry the differential up. If it is separated then replace it.

In the bottom of the picture you can see what looks like 2 pieces of plate welded together. Anyone know what they would be for? I took a similar piece of my car. It was only held on by 1 loose bolt and didn't seem to be doing anything.

It is a harmonic weight. Some of the later models have them.

its a 74Z 2+2 .... sorry bout the bad condition of the picture,since im using my phone camera theres no flash ...Yup the rubber has gone off from the metal & i just found that this was the one which makes the vibrating/knocking sound when i reach 75mph not the rear wheel which i posted weeks ago.So what do i have to buy to replace it? is it the steel solid differential mount? Code : 10-2296 at zcarparts.com

Thanx Peeps

I don't recommend that part for street driven cars. Without any rubber or other material in that part to damp noise and vibrations, your car will be noisier. That part will work, but you may not be happy with the resultant noise and vibrations that will be tranmitted into the body of the car.

Just my opinion.

So what is the right part to replace it?

Agreeing with Carl on the solid diff mount, I wouldn't use those for any application.

What you need is an OE type differential front mount.

Bambikiller ... i cant seem to find 10-2252 ... is it from the catalog? Anyway thanx Dude

[Bambikiller240]

Yess, that is the number I found on Page 79 in my catalog from MSA (www.zcarparts.com)

It is not shown on their website because they have not published the "Drivetrain" section as yet.
