I should preface this with saying that the 850 is running Bilsteins(all the way around)/TME lowering springs/Voxx 17" wheels/Micheln 215/45/17s/IPD strut brace/Volvo camber kit. <p>My father is feeling a light vibration in the steering wheel when he is traveling over 65mph on concrete-on asphalt he is says he can't feel the vibration. After assuring me that he didn't think the vibration was coming from the stiffened springs/bigger wheels/less tire rubber(as compared to the stock tire) absorbing energy, I went to work(with my mechanic) trying to ascertain what the issue could be. Both end links were replaced, the shock/strut mounts were checked, the tie rod ends are less than 2 years old, the wheel bearings are good, and everything in the suspension seems nice and tight. <p>The car was in for an alignment less then 1k ago, and at the time had all the wheels balanced. When I was washing the car a few days back I noticed that the weights had come off the front passenger wheel, so back I went to Big O', and ten minutes later the wheel was balanced(w/ new weights). Any help would be most appreciated. Thanks!

You always will feel a little shake on concrete. If it's fine on blacktop the car is fine.<br>It <B>IS</B> the Bilsteins <B>and</B> the springs and the ...... (you fill in the blanks).<br>If it was stock with 15's or 16's he wouldn't feel a thing.<br>It could still be a tie rod, could be the steering rack, it just could be any litle thing<br>(plus the HD's).<br>Stop modding your dad's car <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/sly.gif" BORDER="0">

Re: mild vibration in the steering wheel when driving over 65mph..... (JRL)

Thank you JRL for the help <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> I just spoke to my dad, and I got a little bit of clarification. Apparently, on asphalt, the car is experiencing a "little" vibration, while on concrete the vibration is more pronounced. The car is getting a new(rebuilt) steering rack installed on Tuesday morning, and in then in the afternoon it will get an alignment and balancing, so we shall see if that solves the problem. If not, I will have to take the car to the local suspension shop and have them give the front end a going over. Have a splendid weekend one and all <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (JRL)

The steering rack has minor seepage, so I used my parts place and got the rack for $350-some $250 off retail. With labour, the job will come to $600-no biggie there. Once the job is completed, I will have the wheels balanced and aligned, and see where we stand at that point. Thank you JRL for all the great advice, and I will report back on Tuesday evening once all the work has been completed. Have a wonderful weekend one and all <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (1sciroccofahrer)

You should have asked first, $230 from fcpgroten, retail, I pay even less.<br>Still, I don't think a lightly wisping rack will cause any shaking.<br>You play, you pay. The 17's alone can cause minor shaking<br>The car is modified , hence it won't ride like a stock car and besides, that thing has so many miles on it you should be happy that it runs as well as it does

Re: (JRL)

I have had a bad expeirence with FCP Groton, so I don't use them anymore. I could have purchased the rack for about $80 less, but I was throwing some business in the direction of a friend. The 17s did cause the ride to be more harsh then with the stock 15s, but the vibration my father is feeling (at least he contends) is something different then the heavy duty suspension and wheel/tire package. <p>As to the car having so many miles on it that my father should be happy that it runs as well as it does-that mentality doesn't work for me. The body of the car is not at issue, but rather mechanical parts which CAN be addressed-so any logical mind would try to ascertain what is causing the issue, then try to address it. Thanks for the help! Cheers <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> <BR><BR>

The tyre may not be sitting on the rim correctly, it forces the tyre slightly out of round, happened to me once with the mags on a ES300 Lexus, balancing will not pick it up as the problem is from top to bottom as it were, not side to side, they had to break the seal on the front tyres from the rims, rotate them and reinstall them in another spot. <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0">

As said, it could literally be any one small thing.<br>Have the tires FORCE balanced, that way if one is bad, it shows up on that machine

Re: mild vibration in the steering wheel when driving over 65mph..... (JRL)

Thanks JRL and Cocka! I will have a lot of info at my disposable on Tuesday afternoon when I take the car in to have the wheels balanced.....hopefully I can get the situation corrected asap. Have a splendid weekend <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0">

FORCE balancing, that's the ticket!<p>My mechanic uses that procedure, it works wonders! You will get a read-out of the actual before and after wheel balance.<p>Also, there is the issue of bushings. control arm bushings are known to "go"<p>Then there are all the bushings associated with the rear trailing arms. Time has a way of slowly killing the bushings. The stiff siuspension accentautes this and all imperfections.<p>You say the your Dad notices the vibration, how 'bout you? Do you have the opportunity to drive the car?

Re: (RussBert)

I will make sure that the wheels are force balanced on Tuesday, and then have my father road test it and see how it feels. From time to time(i.e. taking the car to the mechanic) I do in fact drive the 850, but after driving my VW Scirocco, a big rig would seem like a smooth ride <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> Thank you one and all for all the help and kind words, and I will report back Tuesday (hopefully) with good news. Have a great holiday weekend <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (1sciroccofahrer)

I sort of had the same problem with my 850 last month.<br>On certain types of road surfaces it shook just a little.<br>Naturally this drove me nuts.<br>I know it wasn't the "car" as everything is new including the tires, so that is where we looked.<br>As I said, force balanced them and we found one tire that is just "a bit weird" so that one went on the rear (along with a couple that were off by maybe 1/4 ounce.<br>It still shakes a bit but only when cold, after about 3 miles of driving it's as smooth as silk

Re: mild vibration in the steering wheel when driving over 65mph..... (1sciroccofahrer)

Had another thought, it could be a "lumpy" and/or badly made tyre (doesn't depend on the brand either it happens to the better ones too) sometimes when they get worn down a bit this happens. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

Re: mild vibration in the steering wheel when driving over 65mph..... (JRL)

I had the wheels balances and aligned (after having the steering rack replaced), and after driving to San Francisco and back, my father believes that the problem has been resolved. I will consult with him further tomorrow, and come back and share his observations. Thanks again one and all <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">
