I took the OP's word on multiple balancings being done and should have revealed a bad rim situation IF the person doing the task watched the tire AND wheel spin. One would not expect to see a bad aluminum rim unless a very noticeable bend from say a curb hit or severe pothole. I did countless tire changes and balances in my day and always watched how the tire and rim for "wobbling" as they spun in the balancer. Also an unusual amount of weight being needed to bring a tire "into balance" should be another "tip off" to a tire or rim problem. My standard was anything over 4 ounces on a passenger car tire was cause for further investigation. My apologies to our metric standard members for not giving the metric equivalent, but I think you will understand the "gist" of my posting.

John/Horace Posted 18 hours ago Report Share Posted 18 hours ago Some of us grew up on imperial and were made to switch in grade school, when feds brought in metric. I still keep house thermostat in Fahrenheit, finer adjustment. The calculator on our smart phones is great for converting, so 4 ounces is 113 grams. Yeah hate seeing huge weights on a tire. Tire with largest weight usually goes driver rear, farthest from steering wheel. Most weights double marked, here is pick of a 1oz or 28 gram and a 1.5 oz or 43 gram. Four oz would be huge, around 4 inches, but I have seen them used. Quote Link to comment Share on other sites More sharing options...
steve lada Posted 17 hours ago Report Share Posted 17 hours ago 10 hours ago, John/Horace said: Sounds like a frustrating problem, at least the stuff you have changed out are wear items. If you keep the car you are ahead. You could paint mark all flange connections where driveshaft bolts up; then index the flanges and bolt together again. Or if you have the old shaft you could try reinstalling it. But before reinstalling another driveshaft try driving the vehicle up to vibration speed. If it’s gone you at least have the source. Driving without shaft may trigger a dash light, some people unplug the connector feeding the rear diff. It’s the coil power source for engaging awd. When changing drive shafts mechanics usually mark current location. But with a new shaft it’s not an option. Some shops do have special vibration analysis tools for trouble shooting tricky problems. I do not have the old drive shaft. the carrier bearing was clearly worn and rusted, and i was certain this problem was solved. not to be...now the mention of shops having a special analysis tool has my attention. I have never heard of such a thing but my eye balls are wide open. my 2015 is soon to be a 2025..............would love to find this to help another guy. I was even gonna go back to the mechanics shop and fill him in in case he ever had one like this. its probably gonna cost me more than the damn thing is worth....but now ..I'm pissed.

steve lada Posted 6 hours ago Report Share Posted 6 hours ago you are right about one thing,most are wear parts. so my 2015 is almost a 2025! all of the wheels have been checked many times on a high speed balance machine. John,are you saying try driving without the driveshaft connected? hmmmmmm and letting the front wheel drive take over??? I never would have thought of this. but can this really be done?

Yes it has been done by several people on the site for trouble shooting. Safe, doesnt hurt anything. This facebook link to Royalty Auto Surface(good info site) shows chasis vibration sensors locating problem. Not all shops have this equipment. When I worked as a millwright mechanic before retiring, we had vibration analysis tools. https://www.facebook.com/share/v/1FTMQhM1NF/ 5 hours ago, steve lada said: Edited 1 hour ago by John/Horace Quote Link to comment Share on other sites More sharing options...
