Busted axle shaft boot
I have a 2003 Ford F150, 4x4, and i recently installed torsion bar leveling keys, i did not notice before i put the keys on, but while parked level, wheels straight, my wheels stand awkward, the bottom sticks out while the top is kinda sucked in, when i took a closer look, my inner axle shaft boot on my passenger side is busted and slinging all the grease out, has anybody had this same problem, what is the solution?

I had the same problem. Cranking the torsion bars up puts more stress on the cv shafts and boots causing them to split. You will need to put a new boot an repack with grease. You will have to remove axel shaft I believe. You may be able to do it with it still on I'm not sure. I took mine out. It's been a few years since I did mine. I know there is a little snap ring the holds the joint onto the shaft u pull that off an the boot will slide off and a new one can be put on. It's not a hard job to do just time consuming.

And when you put them back in, you will want to adjust the suspension using the factory specifications. There was a thread on it a while back where I posted all the info. You will keep eating boots if you keep the keys cranked all the way up.

Here is the thread with the info.

I agree if you have them cranked up all the way you are going to eat ball joints and cv boots. I had this problem on my truck I previously had. And when I lowered it back down but not all the way everything was fine. Plus it rode a whole lot better the front suspension could actually work it wasnt so tight. Good luck with whatever you choose to do.

It's cheaper in the long run to just replace the axle shaft assembly/s and some new knuckle and diff. seals about $60.00 a side and your labor.

Be careful with that, the inner joints on a lot of the cheaper replacement axles are three-axis/Tripod units and are COMPLETELY incompatible with a lift. It needs to have the OE style six-axis/Rzeppa style joint. Found that out the hard way too...
It is not hard at all to do a boot replacement. If you have the skills to pull the axle, you have the skills to swap the boot. Just don't put a split boot on it.
