Is there a risk of cracking the rear window when jacking up the Model 3 from just one jack point

[mrfiat74]

I read on here somewhere that there was a risk of cracking the rear window on the Model 3 if you only jack it up from one jack point. Is this true?
Has anyone had this happen to them? How about if you jack the whole side of the car up with two jacks at the same time? Thanks.

I can’t say there’s never a risk, but I’ve single-point jacked my car maybe ten times now without any issue (tire rotations).

I drove up an incline in a parking lot once diagonally, so one front wheel first, and there was a loud crack noise. “That was weird, hope it was nothing” I thought. Some time later I noticed that the rear window was cracked all along the bottom. Can’t definitively say it was that event, but…
Replaced window has been fine at the same incline (can’t easily avoid it).
I’d wonder about jacking it from a single corner too.

Is it best to use the front or rear jack point when rotating tires?

Thanks, sorry that happened to you. I will jack the rear and front at the same time from now on. I only have 2 floor jacks, so that is the best I can do right now.

For tire rotations, I jack the front far enough to slip my bottle jack under the rear point, then jack up the rear until the wheel clears.

I also had the rear jacked for a day while waiting for a flat tire to be repaired, with no ill effects. I put wood blocks under the suspension knuckle "just in case", but the Harbor Freight jack held firm.

Since the weight distribution for the M3 is roughly 53% in the rear and 47% in the front, I always jack up the rear.

I've only ever jacked my car up at one point to change wheels. My back window has not broken yet.

It would be a horrible oversight in engineering to suggest that the car can't be jacked up from a single jack point to do something like changing a tire.

Anyway, I did it when swapping out summer wheels/tires for winter ones and had no issue.

Whilst it does seem unlikely to be the cause, I now have a broken rear screen. The crack wasn’t there when I drove the car yesterday and the only thing to have happened in the meantime was jacking to lubricate the brakes. The car was parked off road and under a car port

I have a wheel in the air all the time and never had a problem... Also have jacked from one point (front, to remove front wheel) and never had a problem.
