My 8.5 +17 in front fit easily and your 9.5 +37 will actually sit 7mm more inward than my setup so I'd say you will be plenty fine up front.
If you want to be sure, get the width/offset of your current wheels and use an online calculator to see how much more in/out the new wheels will sit vs the current ones. 1010tires.com has a good difference calculator.
