Ferrari Mailing List: Re: Suspension Rebuild

If you are using the poly ES bushings, I'd recommend disassembling them.  They 
come apart into four pieces (outer metal shell, inner metal shell,  poly sleeve 
and poly donut bushing).  Then you can weld the outer shell to the A-arm 
without damaging the poly sleeve that sits between the inner and outer shell.  
Re-assemble using the supplied grease.

The bushings are a full floating design, so the inner metal shell (fixed to the 
car frame A-arm mounts) is supposed to rotate with respect to the outer metal 
shell (welded to the A-arm).  Lubrication is required.

Larry,

I'd love to see that picture!

So, should I not even use the lube  that ES supplies? 
I've heard that the poly bushings can squeek pretty bad sometimes.

Hi Jim,
    I always use 2 tools to break them apart - I have a screw type seperator 
that I tighten down - that puts great tension on the fitting - then I use a 
fork tool to whack the ball joint - typically, they break loose in 1 or 2 
whacks -

    I'll try to find a photo of the screw type tool I use.

    Of course, heat will probably help also -
;-)

BTW, I've been told not to use lubricants on any new rubber bushings you may 
be installing, - supposedly they need the grip that WD40, etc removes.

Hey guys,

I'm right in the middle of rebuilding the suspension on the GT4 and 
installing a new 2.5 turn  steering rack.  I'm having a helluva time getting 
the ball joints off of the hub carriers.  I've soaked them in penetrating 
oil and broke a ball joint tool already trying to hey them apart.   Does 
anyone have any ideas??

If you are interested, check out the 308 section of FChat for pictures. 
Ill post some here soon.

Jim
