He's talking about driveline vibrations.. not just normal its an old jeep vibrations.. both he and I have yjs.. he's trying to figure out for you if the lift height has caused you to go beyond the limits of your slip yoke rear driveshaft. Did you shim the rear axle when you installed the lift? Also what's the measurement of the shackle from bolt center to bolt center?
I can't remember what it is I'd have to check but yea I knew what u were talking about sorry if I upset u by being a smartass but yes it does have a lot of vibration and noises it makes a bad clunkimg but goes away as I speed up
You probably are reaching the limitations of your rear driveshaft.. you can do a transfer case drop which can be very cheap.. or do a hack n tap or fixed yoke kit.. all will have varying prices but will help with driveline vibrations
