Does a 1996 Buick Riviera need a 4 wheel alignment?
Yesy, All front wheel drive cars should ideally have FOUR WHEEL alignment. BOB yes I am pretty sure If not I don't know where you live but If you have a car with transmission and a gasket effect on the motor and a four-wheel drive there should be a Auto zone or Transmission Buffalo car shop near bye. sincerely, alley an eleven year old transmission girl that works with her dad and knows alot aboyut cars . For the most part many people do not need an alignment, this is the first thing that they will think is the problem, while most of the time it is something completely different. Make sure all your tires are properly inflated, and then try balancing your tires, that is the more common problem then needing an alignment and it will save a lot of money. The 17 yr old buick racer
What causes your 1996 Buick Riviera steering wheel to vibrate at idle in drive while stopped -no vibration in park or at road speed?
I just had the same problem on my 1998 riviera. Found out it was in the horn switch located in the steering wheel. However, it is part of the air bag module which isn't available any more through GM. A person might be able to get a used one off the internet for around $104.00 or simply have a button installed on the dash and wired in to the black wire coming down the steering…
I'm not sure, but my wifes 2000 Venture had that problem and it was the speed sensors on the front wheels. If the ECM can't determine wheel speed it can't sense wheel spin (a difference between the two drive wheels) therefore it shuts down the anti-lock brakes which is how it stops spinning, (it uses the brakes to stop the spinning). Maybe this is your problem, hope I helped.
