Bad Pinion Angle?

audie.a · Dec 6, 2004

I have a 93 bronco that has a vibration from the rear.I have had this truck for 3 years and it had a vibration at 35 mph before, and now i put a straight axle in front and raised it up more.(it used to have a 4" rancho lift)Now the vibration is worse,I've had the back tires checked and balanced and have had the rear end apart 8 times trying diff shims to get the right angle.Im getting very frustrated!!!!!!does anyone have pics or something else i can try.PLEASE HELP...

Did you replace the u-joints and check the splines on the driveline to see if there is any slop? These are the first places to look. Then the rear end.
