I have a 1050 4wd I replaced the left front hub bearings on and after i got it back both front tires lock up when i drive in forward the front driveline is not hooked up on it so i know its not locked up in 4wd it goes backwards fine just not forwards. also when i pick up the front end and turn the tires they spin fine but when i spin on side forward the other side goes backwards? please help thanks
