Jack stand possible work.... - 986 Forum - The Community for Porsche Boxster & Cayman Owners

....just looking for opinions

Would you tackle header / exhaust replacement from jack stand elevation?

If so how high of a lift did you need.....?

What about transmission mount replacement?

maytag · 10-28-2018, 09:14 AM

Absolutely, in each case.
I haven't measured how high, but I try to top out the smaller jack stands.

All of those projects are easy from jack stands.

These aren't cheap, but worth every penny IMHO. The car is rock solid. I justified the expense against what I saved from the quote my indie gave me for flushing the coolant on our two cars. They have more than paid for themselves. I still keep a couple of wheels under somewhere as backup.

Liftbars

These look good compared to the twisting and wrenching I do to get the car up

Good to hear! You can never be too safe under a car.

On this week's episode of Garage Squad on Velocity channel, they featured a build for a guy who had his car on jack stands and it fell on him. He was then in a wheel chair for life. Don't ever be that guy.

I always wonder about the cause of these incidents. Is it failure of the stand or the car slipping off?

In the case of Escos shearing (double) of a steel pin has to happen rather than load failing a cast jack stand tooth.

The Escos also have a flat top which I feel is pretty difficult to slip off of.....last time I used them up on all four I recall the set up was pretty robust stability wise. It was getting the car up there to the minimum height without using alternate unibody jacking point that was a bit tricky.

Correct, NEVER too safe!

One thing I would NEVER use crawling under a car are those "lift bars". Have seen them in use and completely understand desired concept but no thanks. If one corner fails or pin slips out, the entire side has more likelihood of coming down. Better hope a jack stand catches somewhere on body and holds until whoever is under scoots out but

if not. Separate and secure contact points are much safer in my opinion. /soapbox

Saw same Garage Squad episode as Stone and caught mention of accident w lifted car but missed detail specifying jack stands. Stands or not, that guy is darn lucky to be alive. Similarly, a year or so ago Velocity aired an episode of Fantomworks I decided to watch... IMNSHO Mark from GYC is marginally (ok, a bit more than marginally) less appealing to watch than Drama Dan.

Anyhow, Drama Dan & co prepped a car (Mustang resto-mod of some sort as I recall) for SEMA. Upon show floor arrival something happened to one of the coilovers. Their panties were all bunched trying to find someone w a jack (really at a car show?

) so they could fix issue. Next scene shows Dan clearly crawling under car only jack supported. Couldn't believe my eyes. Thought he was redeeming himself when he started saying how dangerous it was to work on a car like that... but then pissed all away by relating danger only to state of spring vis-a-vis coilover and not fact car was only being jack supported. Really surprised Velocity aired that portion...

In any event, please ALL be extra careful working under a raised car. Double and triple check it's solid, not just jack supported w/ at least one additional failsafe back up... two are evenbetter.

Good luck

You can do almost anything under with jack stands, it’s just tight. If you have access to a lift it’s MUCH easier. We have a DIY shop here that is basically a shop rental, lifts, tools and all. Absolutely worth the 25 an hour for some jobs. Check to see if you might have a similar shop in your area.

BruceH · 10-29-2018, 05:57 AM

I didn’t replace my headers but I did my exhaust with jack stands, no problem. I also put wheels or something else under as a precaution but my stands are pretty solid.

jaykay · 11-04-2018, 08:27 AM

What is the maximum recommended time one can leave the car on stands with the wheels off?

Any danger of unibody deformation?

I can't imagine deforming a unibody using jack stands.

A friend of mine was killed when his '64 Chevy fell on him, so this subject matter is something I take pretty seriously. When I get the car on stands, if there is room I'll also slide the wheels under the car as a safety backup.

Thanks for the advise.....I have to admit that I am always uneasy under a car on stands

I always keep the jack in a location as well. On a level floor, car level and the jack stands where they belong, a Boxster is pretty bombproof really. Getting the jack stands in the right place under the jack points is a funky proposition though, but not too bad.

Bringin this one back:

-What suspension issue can result..

thx for this pic. I have a pair of these jack stands and preparing to raise my 986S for an engine swap. This pic answers my question of how high? Guess I don't need the 2X12 I was thinking about placing beneath the ESCOs. What kind if cart (height) did you use to roll it away?
Thx!

I used a 500lb capacity "lift table" I got from Harbor Freight which would lower to about 10" above the floor so I had to remove muffler & rear bumper etc.

Those look like Rhino ramps up front. Is there enough lip at the front to keep it from rolling off? Were some serious chalks used

I suppose you used the rear jacking points to put ramps under the front tires one side at a time. Then using the rear lower Control arms get stands at minimum height under the two rear jacking points. Then using the central location moved the rear up one position at a time.

I suppose one could use the rear lower control arms as well to get all the way up.....
