If your under budget give the customer a discounted bill ,the smile on their face will outweigh the wheel falling off on the way home....
The back end is really easy on a T25... undo the lower shock bolt, crack off the wheel nuts and jack up the van... arm goes down and the spring falls out Front is more involved, as LEF said... That requires a certain amount of disassembly... probably 45mins to an hour per side Experience... But even then you can get caught out on jobs!!
