Yes, so long as you don't damage or drill into the sheetmetal while doing it, you should be fine. I know people who have lifted jeeps, wheeled the hell out of it, taken the lift off, and turned the jeep in and been fine.
If I put sport utility bars, custom grille guard, tow pkg. and navigation into my leased vehicle can I take it back out/off before the end of my lease and put the original parts back on it?
Please explain?
(This was done on my own with my own money through the dealership.)
