Hi guys…
I was hoping some of you could help me understand what I need to do to remove my driveline vibes while sitting at a light and when accelerating… I think its between 25-30 mph I get a slight vibration. I’m also worried about damaging my carrier bearing by the recent post I read on this subject. I have a FT 6” lift with Custom Leaf packs and Downy Shackles, so I figure I’m about 7” in the rear higher than stock.
I know many have said that the pinion angle and the carrier bearing cause driveline vibes since they are out of alignment. Which in that case you need to either use washers on the carrier bearing or go the more correct method and shim your axle to correct the angles.
Does anyone know what the correct method is to measuring the correct pinion angle? I have looked at Roger Browns site, which contains tons of info, but I’m still a bit confused. Can anyone make it a bit easier to understand what I exactly need to do to come up with the correct # of degrees to shim?
Is it safe to say that you basically need the same degrees of shim as the amount of lift, so in my case I have 7” of lift so I need about 7 degrees of shim? I think I read that somewhere but not sure.
Thanks guys…
