I agree the balance should be checked first along with the general
condition of the u-joints. A lot of jeeps have 4 inch lifts without
these vibrations coming up so there is a strong chance something else
is going on.

I would be inspecting the driveshaft, it's u-joints or even the axle
u-joints behind the wheels.
Front vibes 'caused' by a 4" lift, isn't something anyone has complained
about on this group.

Re: Rotating front pinon on YJ
Thank you for all your responses! I assumed the problem was the pinon
angle because the vibes started at the same time I put the taller
springs on but perhaps that just exaggerated some vibes I couldn't
feel before. I'll check the u-joints and driveline balance to see if
I can find the problem. Thanks again, your advice has been most
helpful!
Take care,
David

Re: Rotating front pinon on YJ
Thank you for all your responses! I assumed the problem was the pinon
angle because the vibes started at the same time I put the taller
springs on but perhaps that just exaggerated some vibes I couldn't
feel before. I'll check the u-joints and driveline balance to see if
I can find the problem. Thanks again, your advice has been most
helpful!
Take care,
David
