I own a 2000 OBW w/ ltd. slip diff.

When the first snow came I had 4 new snows put on, which I found out after were 1 size taller than I had asked for. Figuring that they were all the same size, I let it go. When driving in slippery terrain only, I hear and feel clunking as I turn the wheel. I have searched this forum and it seems like it could be some kind of worn out coupling? Or am I a complete idiot for leaving the slightly oversized tires on?

 

Hmmm...

Wanton

You don't mention the sizes, or mileage on the car, but as long as the new installed tires are all the same size and inflated properly (a couple of lbs. higher in the front) the difference will not cause any problems I could think of. Maybe your U-Joints?

On our MY95 Legacy L with AWD, I went from 185/70-14 to 195/70-14 then to 205/55-16 with no mechanical damage at all.

I think I figured it out. (the tires Are all the same sizes and inflation) The power steering pump is beginning to whine when cold, and I realize that the shudder is when turning...even on some not too slippery surfaces. So, now I have to see if it is the rack or just a weak pump...???
