How do you remove the airbags on a 1991 Lincoln Mark VII LSC?

The ~safety~ air bag on a 1991 should not be serviced by the vehicle owner. Replacement suspension air bags (springs) come with complete instructions (Arnott, StrutMasters, etc). The seller/manufacturer should gladly provide the buyer with a set even BEFORE purchasing the product. This is in their best interest to show you juyst how easy it is to install their product. If not, I'd move on to the next seller/manufacturer. Jack up your car, get to the air bag, turn the solenoid with vise grips, once the air is out turn the "fat" part at the top to unlock it. its kinda like your power steering cap on your car... it fits into place and turns to lock in. Now at the bottom of your a-arm remove the clip around the little stub that you see. kinda like a cotter pin... But like they said go to strutmasters.com and get some springs!!! 219.00 with shipping included and all instructions also. Hey also visit www.lincolnsonline.com

I found the instructions in a Chiltons #26242 book on Ford Escort/Tracer.

The tension pulley that Ford installed really helped as you don't have to adjust the belt.

Why do humans not go through alternation of generations?

Human beings do exhibit an alternation of generations, but the haploid phase is extremely deemphasized while the diploid phase is overwhelmingly dominant. The haploid phase in humans that results from meiosis is restricted to only one cell, either an egg in the female or a sperm in the male. There is never a multicellular haploid structure as there usually are in plants. If such a multicellular haploid structure is required for a true alternation of generations, then humans do not exhibit alternation of generations. The human organism grows by mitosis (the diploid phase) only after fertilization. A plant sporophyte is diploid and it produces spores by meiosis. Humans, like plant sporophytes, are diploid and make haploid gametes by meiosis.
