I have read some posts on a particular driveline vibration that a lot of people have had experience with.The vibration I have starts around 70 and progressively gets worse as speed increases or even worse yet on decell from these higher speeds.It is a cycling/harmonic type vibration that this car had even way back when my Father-in-law bought it from the previous owner......I started out on a quest last weekend to solve my vibration once and for all.
It all started by ordering the differential(pinion mount) bushings that are still available from Ford;( if I could have purchased the diff. cover mount new,I would have replaced it also).I installed these bushings and relocated the driveshaft 180 degrees.The test drive afterwards was considerably better than before,but still there.
Today,I replaced every bushing,(upper control arm-inner and outer,lower control arm-inners and outers,toe compensators links,lower shock mounts,and new wheel bearings).The only thing I didn't replace was the coil spring insulators(they weren't bad).
In the process I found alot of dry rotted,worn-out,even missing rubber in these bushings.I didn't think my suspension was that bad,but...Holy-Cow....
Took it out for another drive and MAN what a difference.The ride quality is 100 percent better right off the bat.So I got it up to 70 on the highway..No Vibration...75,No Vibration...80,No Vibration.I held it at 85 for a while and took my foot off the gas....Absolutely,NO VIBRATION what-so-ever.It's like driving a different car now.I'm very pleased with the results,I'm gonna give her a wash and a wax tommorow,Fill up the tank,and just go Cruisin'......
P.S....Oh-Yeah....Then take it to the alignment shop for a check on Monday......
