					hey guys,
so lately when i turn the wheel it feels like my front diff. is locked together while im in 2 wheel drive. the first time it happened i thought i was in four wheel drive because of the way it was shuddering when i turned but i was in 2 wheel drive. i haven't been able to crawl underneath and check anything because its been 15 degrees lately and i don't have access to a garage.Any possible ideas as to what might be happening? i have not touched anything in my differential and all of my mods are in my sig. thank you for your input.
-Matt
