heavyduty Posted November 12, 2015 Report Share Posted November 12, 2015 Has anyone had to use a sterring stabilizer on a volvo. Have wabble between 50 and 60 mph. Have new michelin tires front and rear. Have centramat Balencer from and rear. Checked tie rod ends and all sterring component seem to be tight. Any suggestions would be greatly appreciated. Thanks in advance Link to comment Share on other sites More sharing options...
Alie&Jim's Carrilite Posted November 12, 2015 Report Share Posted November 12, 2015 I would take the truck to a front end shop and get them to go thru it. How many miles on it? Has anything ever been replaced on the front end? There can be enough wear in the components that a wobble or vibration sets up at certain tire RPM.

roadfitter Posted November 13, 2015 Report Share Posted November 13, 2015 HEAVYDUTY Here is a cheap suggestion, 7 yrs ago I had a similar issue with my front end. My front end guy said before I due anything switch sides with your steers, left to right an right to left. Run them that way for a hundred miles or so and see if it changes anything. If not then we will look into the front end components. I did and it solved the problem. I put another 15,000 miles before I put new tires on, not that I had to. There was no unusual tread wear but age dictated time for new steer tires. Front end guy said that was a common problem that was often remedied by the switch around. I have had this truck 8 yrs now and have over time rebuilt the front end including King Pins. JMHO. Â HAPPY TRAILS roadfitter Link to comment Share on other sites More sharing options...
heavyduty Posted November 13, 2015 Author Report Share Posted November 13, 2015 Thank you roadfitter. I will give that a try. About to lose faith in michelin steer tires. Link to comment Share on other sites More sharing options...
Jack Mayer Posted November 13, 2015 Report Share Posted November 13, 2015 If that does not do it check them for out of round. Link to comment Share on other sites More sharing options...
Mastercraft Posted November 13, 2015 Report Share Posted November 13, 2015 I had front end "features" on ours that took me a bit of time to fix. But when it was fixed, it was really fixed, not just better. I had the hop at 55 - 65 as well. Before I bought it, they checked tires (that were new), new shocks, check kingpins, check spring bushings, check bearings. They told me it was fixed. Flew out to drive it home.....they lied. Took it anyway as this problem can't be that hard to fix. It wasn't, the left front tire was 0.060" out of round. So, that .060" of excitation at the frequency achieved at 60 mph, caused the front end to resonate and hop, shaking the hood and everything. The tire was actually on the rim correctly based on the mold line that goes around the tire near the rim interface, so I had to mock up a tire truing machine. I strapped my router to and X-Y table and with a 3/8" wide bit, trued the tire in the shop....lots of black mess all over me but really went very well. The hop was fixed but it allowed me to notice the next feature, tracking ruts and grooves in the road, always having to tend the steering wheel to keep it on the road. Ok, checked all the normal stuff that moves in the steering system, including the steering box lash adjustment.....nothing. I welded up mounts to put two Rancho steering stabilizers on it .....no difference. Checked the toe in...., it was toed in about 3/16". This was the most difficult thing to fix as the tie rod was set in place with Wisconsin lock tight. 3' pipe wrench wouldn't touch it. 3' pipe wrench with a bottle jack on the end....no go. Only a soaking with 50% ATF and 50% acetone allowed me to make the adjustment. I wanted to avoid putting a torch to it as it may change the metallurgy of my steering parts. Â After this saga, it's fixed. Link to comment Share on other sites More sharing options...

SuiteSuccess Posted November 15, 2015 Report Share Posted November 15, 2015 Also check to see if hub is centered and tires centered on hub studs. Link to comment Share on other sites More sharing options...
Mastercraft Posted November 15, 2015 Report Share Posted November 15, 2015 Good point SuiteSuccess, I think I have seen these shim tools that slip over three studs while installing the wheel. Gets things centered up if the hub alignment feature or the wheel is a bit worn. Link to comment Share on other sites More sharing options...
heavyduty Posted November 17, 2015 Author Report Share Posted November 17, 2015 Jacked up front of truck today and put bar under front tire and pryed up to check for movement. Driver side had none passenger side has aprx 1/4 inch straight up and down on the kingpin. Not really any movement in and out. When they aligned it a few weeks ago they didn't mention any problems. I do not know how munch play in kingpins is to munch. Just trying to get to bottom of my sterring problem. Link to comment Share on other sites More sharing options...
