#15 of 64 Re: How much vibration in the Steering Wheel [bubbaman999]
May 09, 2006 (5:14 am)
bubbaman999, when you drive on the highway, does the wheel shake back and forth if you take your hands off of it? usually when the front wheels are out of balance, the steering wheel will shimmy, giving you a sign. i recently sold my 87 vette, and it had very wide tires on it, front and back. the steering wheel really vibrated a lot, mainly due to the tire size. since the tires on the GXP are wider in front than the back, maybe part of your vibration could be related to that.
if it was me, and it bothered me that much, i would take it to my dealer, and have a mechanic drive it to see if they think the vibration is abnormal. usually if someone that knows how suspensions and things work can experience what you experience, chances are they can pinpoint the problem if there is one.

Yes they "fixed" the balance last week and unless I am on absolutely smooth flawless road I feel every vibration, even not on the freeway. It didn't do that when right off the lot, now has 1500 miles. Have an appointment for thursday, they may put new tires on thinking but will let you know. By the sounds of other folks they don't "feel" the road on their cars.

" they may put new tires on "
NB: The key to getting the same tread design/compound is the GM "TPC" code on the tire - that's how you know you've got the same construction.
Presuming you want exactly the same tire & not a generic brand \ size RE050A . .

I wonder if you're seeing the same issue I've had with my Bonneville.
Even after getting a new set from GM under warranty and a new set out of my pocket, it's still not totally smooth. You can see the last episode of this saga here.
This issue has been reported by owners of other cars as well, such as the Bonneville's siblings, the old STS and Park Avenue. It seems that as these cars got a stiffer chassis, this issue flared up.
As the vibration is not all the time in my case, I wonder if it's something else...

Thanks for the info. They looked at the car Thursday and then they drove several on the lot and said that the car seemed normal. They were not planning to do anything. Checked the balance and they wrote it off as a "high performance car" with a good road feel and excellent handling. Don't know what to think, the vibration is slight and varies based on the road surface. Maybe I am being too picky, but my 03 Civic SI that was $17K didn't have any vibration at all on any surface. My 1999 Impala LS didn't either? I will look that link and thanks again for the info. Will keep you posted on its status. I have a long vacation coming up in July and see if it drives me nuts.
#20 of 64 1994 Grand Prix Power Steering Line
Oct 22, 2006 (8:01 am)
I have a leak in what appears to be steel tubing in the return line of my Power Steering system. The problem is that the line does not show up on any of the parts dealers parts list that I have visited. It is about a 3/8" OD steel line that has 3 or 4 waves in it a couple inches apart and about an inch or two high. It is clamped to the underside of the vehicle and makes a loop then the input and output turn upward where they connect with the return line from the rack and to the return side of the pump. What is it? can it be replaced without the other two lines? Or, does the whole shabang come as a unit ? Can I omit it and run the return line directly to the rack?
Thanks for any help,
#21 of 64 Rear wheel alinement
Nov 16, 2006 (12:14 pm)
I have recently purchased a 1999 GP SE-3800 with 85,000 miles. As it was used I have no record of repairs. Giving the car a once over I find that the rear tires are wearing very thin on the inside tread. Is it possible to have the rear wheels aliened? The car seams to have been very well maintained and may have replacement struts in the rear.
#22 of 64 rear suspension bounce
Nov 23, 2006 (6:54 am)
I am a new 1996 grand prix owner. The car continuously "bounces" in the rear. Even after new struts and tires were installed. Is the fiberglass mono spring a replaceable and serviceable item? Could that fix my problem?

on my 96 grand prix, when I installed the rear struts, I had to have the rear wheels aligned. I did a 4 wheel of course.But yes, the rears are alignable.
Hope that helps.

I have a 2004 GP with 75,000 miles on it. I've had zero problems with it, but just recently noticed a slight tapping/twinging type vibration that I can feel through the steering wheel when I make turns. It occurs mainly when I'm making a slow turn onto a side street and it doesn't make any difference if it's a left or right hand turn. With each turn I can feel the vibration 2-3 times during the course of the turn. Also, it doesn't make any difference if I'm braking or not, I feel it both when braking during a turn or not. The car tracks straight as an arrow and I'm not seeing any premature tire wear. Any ideas at what this might be or how to check it out?
