So now that my XK has the proper rack& pinion in it and all is right in the world of steering, im turning to my attention to the slight vibration that ive had since ive purchased the jeep. It happens at about 70-75mph, sometimes feeling more severe than other times. Thought it was the tires, but when I put the new ones on when I lifted it it was the same. Ive rebalanced them anyway and stiff have it. Is there any reason I cant pull the front driveshaft and take it for a test ride to eliminate it a possible cause? Thanks in advance for any advice.
