Hi,

I have a 2001 Nissan Sentra. The problem I have at the moment is that at
around 55 mph (90kph) there is a vibration similar to what you get when a
wheel is not balanced. I have had the wheels balanced three times but the
vibration is still there. It is not noticeable below about 50 mph or above
60 mph. only in that narrow range around 55 mph.
Prior to getting this problem, the wheels were replaced by Nissan under a
recall. After the replacement, I didn't really notice any vibration. A
little later, I had new tires on the car. Still no vibration that was
noticeable. It was only a few weeks later that my wife was driving the car
and told me about it. Since that time, it has been very noticeable. The
vibration is quite bad.
The only other thing I have done is to replace the front rotors but the
problem didn't appear until some time after that. In other words, I can't
tie the vibration in to something that was done to the car.
Any ideas what to look for?

Thanks - Pete

i would check and repack the front wheel bearings or replace them
alltogether...just my 2 cents

Dont stop at the bearings- Do a CAREFUL check on all the front end parts.

Maybe ask the wife how fast she hit the kerb and what side ;-)

Hi again,

I just checked the front end out (the first mild weather we have had
recently;-). I found that the passenger side McPherson strut is weak. It
allows the car to bounce about four times before settling down. The drivers
side barely bounces when I do the same test. It looks like that is my
problem.
What do you think?

Thanks - Pete

FWIW I had a Nissan Sunny (B11 chassis) once that was rather sensitive to
wheel balance, it had to be spot on or there was a lot of vibration, but
after changing the front dampers (shocks, struts whatever) the vibration
dropped a lot and was much easier to get balanced.

I have had problems in the past with struts that wore out prematurely
and had a LOT of side-to-side play, so you could have found at least
some of your trouble.

That's a good suggestion, My son had my sentra out one night. Didn't say a
word to me about hitting the curb, next day I was driving, yep vibratons and
rocking back and forth of the steering wheel (left to right). Turns out to
be a bent rim. Just my 2cents.
