[T3] Since I replaced the runner boots and all vacuum lines noticed

[William Jahn]

It seems it doesn't take long for the rubber to become hard. My 73 was 12
years old when I got it , it was 13 when i started to drive it a little
still had my old Ford van until 91 when it became my only mode of
transport. . I recall it vibrated the first time I drove it and it seems to
have gotten a little worse since it was just the right window that I could
hear now I hear and feel the left. I don't know the history of this car.
When I first got it off the used car lot where I worked at a small ford
dealership it had that stick on wood panel stuff on both sides yet the
drivers side was dried and cracked and most needed to be sanded off I
removed the right side with a heat gun. It seemed it sat in one place for
some time and that someone who did painting for a living owned it due the
the paint and paint can rings on some of the rear cargo area. I only found
a few VW dealer receipts under the rear seat.  As I said with the engine
idle lower so it would be 850 to 900 RPM in drive the vibration only stood
out idle in drive as soon as I removed my foot off the brake it was gone ,
now it hangs on until I start moving or place it in neutral , I have no
idea what they were like new either, probably better I've only been in one
other type3 a 68 fastback FI stick and it was close to new at the time and
seemed to have good power even with 4 people. I don't see any cracked sub
frame rubber at least from what I can see yet the ones I can get at are
rock hard. I don't know if one can even get replacements or if I care to
deal with replacing them. I think there are 5 , 2 are above the rear
shocks. If I can cure some of it by replacing the rear mounts and lowering
the idle that would be great , the trans mount is another story you can't
remove it without removing the 4 long bolts and lowering the trans end down
quite a bit to slide it off the 2 trans threaded studs.
