[FC] Forward Motor Mount (Powertrain) Replacement

[Ken Hand]

      First off the forward mounts that are mounted to the cross member 
are bolted. You should be able to cut the nut off and have the mount in 
your hand when it falls off.

     Well, I'm sort of getting ahead of myself here. Jack up the trans 
and diff hold them up with a jack stand at the diff or trans. Remove 
the trans cross member to gain access to the rubber mounts, then cut 
the bolts and off falls the mounts.

    On a car it can be VERY difficult to get a new nut on top of the lip 
of the cross member. All it takes is a finger to hold it while you get 
the bolt started and then use the impact to tighten everything. It's 
been a while since I have done an FC but I will look at the one in the 
garage tomorrow and see what it takes then report back here unless 
someone has already given a definitive answer.

Subject: [FC] Forward Motor Mount (Powertrain) Replacement










I recently noticed that the engine/powertrain on my Rampside was 
leaning toward
the passenger side.
Upon closer inspection, the passenger side forward motor/powertrain 
mount has
rusted thorough right around the round part leaving the mounting flange 
still
bolted to the rear crossmember.

I'm pretty sure that there is enough room to remove/replace the 
motor/powertrain
mount without removing the powertrain, but I'm not sure about the right 
way to
remove the bolts/nuts and old mount.  As you might have guessed, the 
bolts/nuts
on the old mount flange look very rusty.

My first thought was to chisel/break the bolts off but from the FC 
assembly
manual it looks like one or both of the bolts are secured by weld-nuts 
up inside
the crossmember.  I'm concerned that I would end up with broken bolts 
still
remaining in the crossmember weld nuts.  I could also buy/rent an 
oxy-acetylene
torch to try to free the bolts.

Any suggestions would be appreciated.

Thanks,

Scott Wilson
