I took my car to get it corner balanced, and all seem to work out pretty well. Then went to get the alignment and had some issues. I posted about that and got some really good feedback that will help me solve the problem.
Then today as I was looking at the situation again I noticed another problem. The ride height of my car is higher in the passengers rear than the drivers rear by 2.5 cm. I don't know how I or the shop that did the corner balancing missed it. Here are the numbers from the weighing LF 599 RF 541 =1140 LR 724 RR 678 =1402 Total weight 2542 Left side is 52% Right Side is 48% Cross weight is 50.23 To Correct the balancing, take the weight of the total of the front and multiply by the corner to be corrected: 1140x52%=593 for the LF 1140x48%=547 for the RF 1402x52%=729 for the LR and 1402x 48%=673 for the RR Corrected quadrants LF 592(-7) RF 547 (+7) LR 729 (+5) RR 673 (-5) Since I have steel flares, I measured the height from the floor to the lip of the flares and they are the same. I also checked the height setting on the shocks (Bilstein Sports) and they are equal to each other. What would make the car higher on one side? Could the sway bars cause this? It seems one option would be to raise the LR to not only equal the weight but correct the ride height. The only thing that puzzles me about that is that the shocks would be set in two different positions, is that normal?? |

It might be higher on one corner on purpose
I mean they might have jacked up one corner (or down another) to get those numbers so equal and sacraficed appearance to get it. i have a car that has been tapped a few times and is not bent, but has a quarter panel put on about 1/2 inch wrong. I can corner balance the car to get the weight equal as it sits on the contact patches and then the fender looks wrong.... or I can muck with the ride height to get the fender to look correct and then the corner balance is no where near balanced.... my guess is that the car looked good before, and that the corner balance process involves jacking up or down each corner until the weight of the tire on the ground (scale) is equally distributed.... that made your one corner "look" off if you change the "look" back to before, you loose your corner balance. A second thing that I've seen/done is to forget to lock the adjuster and have one corner change due to use or vibration and then the car looks jacked wrong.... but it sounds like your had the two process done shortly after each other and probably haven't put enough miles on it to vibrate out of adjustment yet. brant |
