2015 gt pp floor jack points

[davidw76]

The differential is designed to carry the full weight of any rwd or awd vehicle when its on the ground. If it couldn’t, the axle tube would break. So we know it can carry the weight of the car when it’s in the air, too. Id venture to guess ford puts it in the manual for safety reasons, because people are stupid and would find a way to mess it up. We do it plenty at my dealership.

Yes, if there is a live rear axle then all the weight rests on the axle tubes via the springs. But we are talking about IRS.. there is no weight on the diff when the car is on the ground and there is no solid axle tube either so not sure what you are talking about.

And the issue is not putting weight on the diff. It is putting weight on the +horizontal+ bolts that attach the diff inside the sub-frame. I guess if the bolts are torqued up properly then this might be OK, but I don't think they are designed to take the weight of the vehicle.

Im aware the difference between irs and live. It was more of an example for the people that think you should never lift by the differential ever. Maybe I should have elaborated. I did own a termi and I never had issues doing it.

Sure, I use the diff/axle tube to jack up my jeep all the time. I would have no hesitation to use that technique on any solid axle that is obviously designed to take the full sprung weight of the vehicle.

For the new IRS Mustang, I am 95% sure you would be OK doing it. But I just don't see the point when you can just back up onto ramps in two seconds. Even if Ford said it was safe, ramps would still be a better solution unless you need the wheels off.

From a 2006 owners manual:

I can't speak for others, but here is a pic of the diff. It is mounted to the subframe by four screws so when the car is jacked up at the diff, at that moment the four screws are the only things that are used to support most of the weight of the car, which to me too risky. In normal operation, the subframe mount points and the suspensions are meant to support the car, the diff only has to withstand the lateral force from the torque of the turning drive shaft.

The pic below shows that each side, there are two main side rails that serve as the main support for the car structure. You can jack up at one point of the rail then put the jack stand on the other. As long as the jack point at the main rail, I think it should be OK.

As a long time tech and very familiar with the old jack lift at the pumpkin routine. And do it on my SA vehicles everytime I rotate tires. My take is.... And it is only my take....

A solid axle setup is designed to hold the vehicle weight.

An IRS is not. The pumpkin is mounted solely for itself, not the weight of the car. That's the job of the control arms and Id suggest lifting at those points, if you don't want to use jackpoints.

That's how I handle lifting my IRS vehicles. Not to say you couldn't get away with lifting by the diff, but I won't lift mine that way.

Thanks for looping me in, USPSALIMITED.

Officially, jack stands are only needed when repairing the vehicle so I'm unable to share the best way to place stands. However, that information is available in the Work Shop Manual; access to it can purchased at Ford Motorcraft.

Due to the modification aspect of this thread, I'm going to run away now. :bolt:

Jack under diff. Easy as 1-2-3.

NOT this^^

The diff is NOT designed to take the loads seen while jacking up the entire car. Please don't use the diff on a car with IRS.

If you look under the car, there are four jack points on the body seam weld indicated by arrows on the plastic rocker panels. But there are also about a half dozen spots in total, per side, where the rocker panel has a cutout to access the body seam weld. You can use a floor jack on one of the 4 indicated jack points and place a jack at the next closest cutout, or vice versa. I have done this multiple times to install my exhaust and there is zero damage to the seam weld.

This^^^

agree it should be a sticky

I have read most of those and they usually follow the same pattern..

OP.. "How do I jack my car up onto stands to install my new catback?"
smart ass after 2 seconds.. "RTFM!"
someone else who actually thinks about it.. "its complicated..."

then we get the same discussion

anyway, the simplest answer for most jobs is to use ramps so someone sticky that!

No. While I appreciate you going all OCD and everything, I am still using the diff to raise the back of the car.

Referencing a 2006 diagram without including the info that the main reason for not using it on them was worries about bending the diff cover and causing a leak was pretty smooth. Irrelevant, but smooth.

So just no. You do it your way, I will continue to do it mine, and I won't tell you to close the thread and shut the f$ck up.

Anecdotal evidence: I have raised my car at least 20 times to date by the diff, with both the stock bolts and the Steeda bushing kit, with no issues.

Assuming you don't have the BMR jacking rail, the best places to put stands are the four jacking points described in the manual (just the two rear ones for installing an exhaust). The problem then is.. where do place the floor jack? You could use the diff, opinion is divided on whether that is safe or not. Or you could just use ramps and avoid the jack/stands altogether. Many people have installed their cat-back this way.

I used these...

http://www.walmart.com/ip/RhinoRamps-Black/19526658

They fit fine with the stock PP suspension, for backing on to (exhaust install) or for driving forwards on to (oil change)

Lowered cars might have a problem but then you could just use some wood as "steps".

Thanks man, very easy and properly explained answer. Im actually going to look into the ramps now. I have a jack, stands, and chocks, but i would love to avoid using my jack personally.

congrats bud, glad you took it personal.

I believe the actual main concern that Ford put that warning in the 2006 manual was that jacking the entire half of the car up from a single point increases the risk of the car unbalancing, falling, and crushing someone. Safety is always the manufacturer's priority.

This isn't your thread and I wasn't speaking to you, but all the young guns that want to have the same discussion over and over, ad nauseum.

Glad to hear you've put loads onto a complex piece of machinery that it wasn't designed for, over 20 times. Please comment back in 5 years and tell us how that worked out. In the short term, I'm sure you'll be fine. That's not the point.

If you have actual manufacturer's recommendations, design specs, safety factors, load ratings, extensive use and knowledge of the S550 platform or other valuable pieces of data, please, by all means, share with the group.

Not taking it personal, just utilizing the same smarmy style of your post. You are fairly new here, but immediately get snarky with people asking questions. You cannot be the Search Jeebus, people will ask questions over and over again. It happens on every forum, everywhere.

So I appreciate your input, but dislike the style with which it was imparted. Your call whether to get your panties in a knot over it.

This topic is one that is as heavily debated just like the S550 vs. 6G Camaro. Grabbing some opcorn:
