i will be taking a pair of m/t tires to the track this year and i need help with changing them. can i jack the rearend up on the differential and change them both at the same time? the owners manual said not to do it that way. i thought i read on here that someone has done it. i have ground effects and i was hoping to make things easy. thanks

 

Ford says not too. but most guys do. in fact yesterday my speed shop jacked from there when they need to get under the car to make adjustments

 

Meeehhh.. it's POSSIBLE, but you really shouldn't.. I've seen guys both destory differentials, and punch holes in gas tanks/trunks by doing that if/when the thing slips off the jack.. If you're using the factory jack that came with the car, there are indentations on all four corners of the frame that were intended to be used as jack points..

If you're using a different type of jack you could use the differential, but I'd be careful broham..

 

i have a 3 ton floor jack that i will be using. I was planning to chalk the front wheels. i want to be able to change them both at the same time if possible.

 

Well as long as your aware theres a possibility that you could flex yourdiff. housingand your willing to take that chance your golden.
