ericem Posted February 16, 2009 Share Posted February 16, 2009 Hey. Trying to verify a issue with my 94 SS. I am going to get new tires during the week. Right now the car has newer tires upfront then the rear both the same size, but I did not actually measure them and the are different brands. Now this is what I notice, the car does not seem to roll as well as my 93 wagon does. Seems like something is dragging, and sometimes it feels like something is causing the car to surge when driving at the same time I get vibration in the steering wheel. I am thinking maybe one or w/e tires are damaged, and since there are two different tires, the surging is from the rear wheels and front wheels spinning at a different rate as well as creating drag since it is a AWD car. Does this make sense? Overall the car does not seem like it is getting the fuel economy it should.Anything else I need to look over? Also my one of my front axles seem to be clicking sometimes, but no broken boots. 94 Legacy SS 192,000km 93 Legacy L 324,000km Link to comment Share on other sites More sharing options...
rtcaravan Posted February 16, 2009 Share Posted February 16, 2009 your front axle clicking is prob a broken or cracked cage in the cv joint may cause a prob but not likely. my guess would be the tires because not all tire companys make tires the same size even though the tire size is the same. the outside dia. will most likelly be diff. witch will make your rev. per mile diff. and could be doing what your saying. hope thats some help.

edrach Posted February 16, 2009 Share Posted February 16, 2009 AWD transmission requires that both the front and rear tires be almost exactly the same size. Resolve this descrepancy immediately or else you'll ruin the viscous coupler in your transmission. The coupler is a $575 part from Subaru plus the installation cost! Not something you want to mess with. The drag is normal if the tires on both axles are different diameters. You'll find that going around corners (sharp turns) will cause a "thump thump thump" due to the tires rotating at slightly different speeds.

ericem Posted February 16, 2009 Author Share Posted February 16, 2009 Cornering isn't really a issue, just driving it feels like something is dragging. I recently did all 4 discs and calipers, and greased up the sliders well they all looks perfect too, the steering does not pull either. I found a set of impreza rims with the stock bridgestones, for now ill use them, and later Ill get some new tires. Atleast it will have 4 of the same size tires Thanks guys!
