My 86 turns 2 1/2 turns from lock to lock. It turns real well to the left but it will not turn at all to the right. (The best I can get is straight ahead.) I think the coupler on the steering shaft (from box to steering column) came loose and now it will only turn left. When I turn the wheel 2.5 turns to the left, the left tire is pushed back into the fender. The steering wheel has gradually become off center about 3/4 of a turn (during the last 3 mos.). I put off fixing it and then my buddy used my Blazer while I was out of town and now it is sitting at work needing repaired. Any tips would be greatly appreciated.
