ok if i dropped it from the subframe some questions.
1. how do i get the car up high enough see below
1a how high should i get it
2. what do i need to unhook exhaust, struts, wiring, steering column shaft
3. what do i hook from see below
4. what do i need to remove for parts
i have never dropped a vehicle from the bottom before
My opinion and experience: Much easier to pull out the bottom.
Here is what I did in my garage:
1. Rear wheels up on ramps
2. Jacked up front end with floor jack.
3. At the end of the jack stroke, I placed heavy duty jackstands under the subframe.
4. I then continued to jack up using 4x4 blocks between the jack and the subframe.
5. I then placed a double 4x4 across the body just aft of the subframe mounts. The 4x4's were supported by the heavy duty jackstands.
6. Disconnected all hoses, wiring, upper strut mounts, steering shaft, and cables.
7. Using the engine hoist with chains, supported the engine/trans
8. Removed subframe mounting bolts
9. Lower subframe with engine/trans onto a 4 caster dolly
10. Removed assembly from under car
This now allows you to remove the engine/trans from the subframe, replace subframe bushings, and clean and inspect everything. You may also want to paint the subframe to prevent rusting.
Removing the engine/trans this way is about a 4-5 hour job. Reinstallation is just opposite. The actual bolting up didn't take long, it wall all the reconnection of wiring, cables, etc that was time consuming.
I also used this same procedure to replace the engine in my 2002 Olds Silhouette van last summer.
