I want to raise my '86 SIII front end on jack stands for some oil change work, rack inspection and suspension assessment.
I am thinking of having two 2x6 pieces of wood, 38 inches long, nailed together, and placed from lower spring seat to spring seat
along the lower cross member.
Then I want to use a high lift jack in the middle of this timber cross bar to raise the car high enough to place jack stands at each end,
basically under the spring seat positions. In my mind, I think this will provide peace of mind as I crawl under this gravitational beast!
I use jackstands under the forward position subframe mounts, the round section where the six-shooter bushings go. These drop nicely into the jackstands and, being far forward, are mostly out of they way when working under the car.
But there are a hundred ways to skin a cat
No matter what method you decide I always suggest taking off a couple wheels and putting them somewhere under the car. Or big blocks, or your drive-on ramps, or whatever. That way, if the worst happens, the car does not pancake right down to the floor .....with you underneath. Thus there is some chance of survival.
The six-shooter bushings are #10 in the illustration below. A giant bolt runs thru 'em.
A spacer (#13) establishes a gap between the subframe and the tie-down plate (#15). The bolt goes thru the spacer as you can see.
Put your jackstand under the spacer. The jaw of the jackstand (mine, at least) allows the spacer to drop into place nicely and is securely captured between the subframe and the tie-down plate.
First pic shows the biggie bolt and sleeve betwixt the tie-down bracket and the six-shoot bushing. Second pic shows the same parts engaged with the jaw of the jackstand
Just a word of caution, Doug's jackstand position is great, as the chassis, not the actual subframe 6 shot extension is taking the weight. If you place the stand under the actual subframe extension itself, it will very likely bend.
Thanks Doug, I think I'll be using you method from now on. Much better than the wood blocks with hole for the jack peg I've been using. I've also noticed when using stands at the 4 jack pegs that the front doors don't close as well due to slight body flexing. Think your method will cure that annoyance.
This was excellent Information we received back in December. In thinking about it this morning (my mind runs slow) where is the best place to put the REAR Jack stands? I have been using the jacking points in front of the back wheels. Thanks for your help.
