Need help for reference for silent block of MKIV
« on: September 22, 2018, 19:18:11 »
Dear All,

I have an MKIV (AK1317)  and I spotted that a silent block is dying.
I have attached 2 pictures to illustrate which silent block it is;

let me try and explain: Under the rear end of the gearbox, there is a piece of metal that supports the gearbox. This piece of metal is clearly visible on the picture -silent block gearbox 1-  At each end of this metal bar, the bar is attached to the chassis through metal legs welded on the chassis and a system of nut/bold - see picture silent block gearbox 2- In order to avoid metal/metal contact and dampen vibrations, there is a silent block in between the metal bar and the welded legs;
It is this silent block that starts to break in pieces.  I have made a drawing of what I think the silent block looks like. possibly it is in 2 pieces i.e. cut in the middle on my drawing

I am actually looking for advice: does anyone know the reference of this silent block and also where to buy it ?

Many thanks in advance for your help.
Best regards

Hello Laurant,

The silent blocks are original Ford Mustang (Fox Body) transmission crossmember bushings from 79 to 93.

Your Ford dealer or LMR.com or cjponyparts.com should have some original rubber parts or PU replacements made by Prothane or Energy Suspension.

Everything should be made as simple as possible, but not simpler!

Great, Many thanks Uwe.

You must know then are they one part or 2 parts symetrical ?
Many thanks

Because of the PU and the flanges on both side of the bushings you have 4 symetrical parts in total for the crossmember
Everything should be made as simple as possible, but not simpler!

You are welcome Laurent,

when installing the crossmember with new PU bushings instead of rubber ones you will need a bit more force to push the crossmember in between the welded brackets on the frame.

Widening the brackets or ears a bit and silicon grease during the assembly will help but You still need some force.
Everything should be made as simple as possible, but not simpler!
