hello group
balanced 440,steel crank,auto,355s.
i have a rhytmic vibration problem @ hwy speed
ive changed third members,two drive shafts,both balanced & rebalanced,brute u-joints,urathane trans mount,axles,axle bearings,convertor,changed tires,wheels,pulled belts,changed harmonic balancer & even told my girlfreind to get out of the car! still no change
except im in the dog house
in neutral it not as bad,but if you rev the engine you feel it in the slap stick.
any suggestions would be appreciated
thanks gil
