Vibrations Simplified

i've been reading a lot of posts about vibrations, so i figured i'd post some GENERALIZED info, most of you probably already know. this is most common causes, and first places to look. mph's can vary in certain cases 10-15mph + or -

if you feel the steering wheel vibrating, vibe usually in front
if you don't feel wheel moving, usually from back

rotate tires to see if vibe changes. driveline probs won't move with tire rotation. if problem moves front to back, it is tire related, not always definitive if problem doesn't move-there's a possibility of more than 1 or 2 tire/wheels causing probs.

Low speed vibration-usually 15-35mph (can vary) = bent wheel, or bad tire-belt/shfited etc....(both act the same) usually goes away at a high enough speed

High speed vibration- usually 50-70mph (can vary) = tire balance, usually won't happen below, and or above a certain speed range. balancing large tires is hard, and weights can fall off, and some guys will say close enough. don't rule this out if you just got tires, or just got balanced.

99.999% alignments will not affect, or help vibrations. if your alignment is that bad, you'd see it with the naked eye. bad alignment can result in uneven/premature tire wear, offcenter steering wheel, and/or pulling to one direction. if you experience this, get alignment.

note: worn tires cause more pulls in my experience than bad alignment.

Alignment= 3 angles, camber, caster, and toe. camber and toe angles will effect tire wear, caster will not-pulling angle only. camber will effect tire wear, and pull. toe will only effect tire wear, and centered steering wheel. none of these angles can cause vibrations. this is long enough, i won't describe what these 3 angles are

tire and wheel vibes aren't usually as sharp, or harsh feeling as drive line.

always check u joints, there's enough info around here about the odd vibes, and DW w/ lifted jeeps, and pinion angles, so i've avoided that, this is long enough.

REMEMBER, this is most common causes, cars do weird things, but these are the first places to go. this is true of all cars, suv's and light trucks. hope someone finds this usefull, most of ya already know i'm sure.
