the front driveshaft on the right of the car (shortest one) of my sierra cosworth 4x4 is couple of years ago replaced by the previous owner now i was today put new grease in the shafts and i could pull the right axle out of the front dif ,normal there''s a clip on the axle so for removing it you must first open de dif casing but mine''s wasn't a clip and there''s no sleeve in the axle to for installing the clip in the dif dont now where the axle came from but is the same as the old one what is the best i can do now the car is running around a few years so with that axle should i buy another drive shaft or is it fine so ? can it come out when youre driving?
