You should be OK for short trips in the winter. But you will need to get this replaced before spring so why take chances. I think the repair estimate is on the high end I would get the part from Merlin mention the club for 10% discount then find a different mechanic who will instal it for a reasonable cost. You can save a decent % when you buy the parts because we get quality OEM from Merlin at a 10% discount and also the mechanic doesnt get to charge you more for the part than he paid without the discount.
