Subject: [Mgs] backing up shudder
Date: Sat, 20 Jun 2015 12:28:20 -0500
Both my A and TD started jumping or shuddering when backing up. I had=
this happen before- seems odd it started again on 2 cars but coinciden=
ce I’m sure.
I searched and can’t find much so I want to know if I’m miss=
ing anything…
Possible:
front engine mount
transmission mount (do I have to take it out to see on the TD?) =
axle U bolts =
TD engine stabilizer
TD clutch (seems like might have been the problem last time but what do =
I adjust here)
Other ideas or what am I missing? I read pilot bearings but were repla=
ced so I doubt much wear. =
Thanks, Mike
