Hello again all! Within the past few months I've noticed that my trusty 850's ride quality has become a bit too harsh for my liking. After driving my mothers '04 S40 LSE for a few days, I grew comfortable with its more forgiving, but still flat around sharp corners suspension. I returned to my 850 today and was very shocked at how harsh the ride actually was. Every expansion joint on the highway, every little imperfection in the road, was extremely harsh. After researching for a few hours, I think my problem lies on my control arms.<p>Now after the ScanTech spring seat fiasco a few months back, I thought my suspension problems were behind me. Well, I was wrong apparently. Just today I learned that my control arm bushings were more than likely needing to be replaced. You see, I torqued the control arm to subframe bolts to spec while the car was in the air. Common sense escaped me I suppose. <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> In that process Im sure I damaged the bushings once the suspension was loaded <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> Not that it really matters because they (control arms) were more than likely shot to begin with. <p>Now, my question to you all is, do you think, or know, that if I replace my entire control arms with either the "stock" control arms offered by FCPGroton: <A HREF="http://cgi.ebay.com/ebaymotors/VOLVO-CONTROL-ARM-SUSPENSION-KIT-850-S70-V70-IMPROVED_W0QQcmdZViewItemQQcategoryZ33583QQihZ018QQitemZ280005147911QQrdZ1QQsspagenameZWDVW" TARGET="_blank">FCPGroton Control Arm & End Links</A> OR the upgraded control arms with Delrin bushings: <A HREF="http://www.quickbrickmotorsports.com/prod_cabushing.html" TARGET="_blank">QBM Control Arms</A> that this will cure the impact harshness as stated in the product description of the QBM Control arms? Has anyone had any similar experience? If so, what should I do first when it comes to replacing suspension parts to cure the harshness?<p>I might also add that I intend to replace the struts, which are starting to show signs of oil seepage in the very near future. Im thinking of Bilstein TC. I would like to correct the harshness, which Im pretty sure would not be caused by aging struts first. My end links, strut mounts & spring seats have been replaced within the last 3 months with genuine volvo parts, but I do plan to replace the end links with ipd's HD end links when I replace my control arms. <p>Please, Id like all input as this is really taking the joy out of driving my 850.<br>Thanks again for the support!<br>-Nathan<p><br>Grrr for a missing M in dilemma <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <BR><BR>

I have the Bilst. Touring (TC's) and like them...they dampen the ride quite well...much better than stock, but they did raise my front about 1/2 an inch. JRL swears by Koni shocks and lowering springs by H&R. The over-all result is slightly over an inch lowering in the front but still a controlled ride that is dampened better than the TC's. Like I said, I like my ride fine...just don't like the way my front is jacked up. Would rather have had some lowering effect.

Re: (MadeInJapan)

Stock springs, Koni (Yellow) are by far the most compliant ride with full control. Bilstein Tourings are 2nd (with a slight RISE, 1/2") in ride height

Re: (JRL)

Great info on the struts! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> Im going with the Bilstein TC's simply because I can easily afford them. <br>Does anyone have any input on the control arms? Anyone ever changed theirs and noticed a smoother ride? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

Re: (JRL)

Yes, the ride height is expected. Not really wanted... but half inch isnt too bad. <br>And I do plan to stay with the stock springs.<p>My car has 141K on it.

Re: (JRL)

Hmm, now this makes me think, you get what you pay for, and it probably costs more money because it saves money in the end. <p>JRL, which type of Koni's would you suggest? Smoothest ride possible is what Im after.

Re: (TurboMoose)

Yellow (standard adjustable Koni)<br>Look here: <A HREF="http://www.shox.com/appguide/shoxshop/productsdisplay.php" TARGET="_blank">http://www.shox.com/appguide/s...y.php</A><p>About $6.00 more than a set of Bilstein tourings, (about right)<br>Very decent pricing

Re: (steve s)

So from my understanding, the harsh ride is attributed to the struts that are on my car now and not the control arms?

More than likely but a bad control arm doesn't help

Re: (JRL)

Rats! Well I guess it's my turn to put some real money into my car. Koni here I come.<p>Would you all suggest the Quickbrick Motorsports control arms or the control arms from FCPGroton?

Re: (TurboMoose)

I have the Koni yellow's and stock springs on my '96 855T. They are both set to the softest setting, and that's where I like 'em best...I've tried many other combinations as well. I am very pleased with the Koni's. I got them for $520 shipped from FCPGroton.<p>I replaced the spring seats (Sachs) and strut mounts (INA) as well. I did the boots and bump stops, too. The rears got new Sachs shock mounts.<p>I have QBM end links. They are the Bomb! very sturdy units. I have went through 3 sets of end links in 4 years. The QBM's should last forever!<p>If I needed new control arms, I would go with QBM's delrin bushed units over any others out there. I did my C/A's last summer, so it'll be a while before they need replacement (I hope!)<p><IMG SRC="http://img.photobucket.com/albums/v432/RussBert/wheelwell2.jpg" BORDER="0">

Re: (JRL)

Well I just got home from dinner... man that ride is annoying. It's like I have no damping at all! I feel everything! Im going to inspect everything tomorrow. This is really frustrating. <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0">
