Knock/vibe after adding coil spacers.

Hey guys,

I added 1.5 inch spacers to my front end to level it out and since then have noticed a knock/vibe underneath my feet driving at about 60 mph to 65, and if I go faster it goes away. I had a wobble in the steering wheel before hand, but pretty sure thats due to my tires being out of balance. Could these go hand in hand with wheels being out of balance? Or is my front driveshaft shot? we did have to remove the front ds to get my front end back together, but I checked and everything is tight and looks normal underneath. I am at a loss, any ideas appreciated. Next step will be pulling the front driveshaft to see what happens. I have stock shafts, 35s with a TF 2.5 Coil lift w/ front adj lower control arms. Thanks guys.

Mike

could be the inner plastic flares slapping the body.

they are affected by wind or a change in aerodynamics. lifting the nose has changed the aerodynamics.

ex: RHD JK 2dr CRD auto
now: RHD JK 2dr Rubicon 3.8 6spd

think you might be right, I noticed a loose plastic clip on the liner on the drivers side, put it back in and my drive in to work was quiet...lol. Must of forgot to put it in all the way after loosening it get to the damn abs line. thanks for the input.

If it's a vibration that comes in around 60-65 then disappears it could be a drive shaft vibration due to the pinion angle.

What drive shafts do you have?

What is your pinion angle?
