Rear Strut Leak

I had H&R F90 Springs Installed last week and everything was great. I had a chassis error code briefly, but that was fixed right away before I took the car home. I got the car aligned as well. Today I had Titan wheels installed and I find my rear passenger suspension has a leak of some sort.

2 pics can show what's going on. This issue only started today when I had wheels installed.

I was thinking it was brake line/fluid but the brake lines are all fine and dry. The silver part of the strut housing is greasy though and the fluid that fell on the ground was clear/oily

Could the strut be damaged?

That is a blown shock.
It looks like the installer damaged the shock during installation.

Thank you. Can I drive the car until a replacement strut arrives and is installed?

The car is a 2020 and has 6800 miles, would I replace just the 1 strut or both?

In this case, you only need to replace one.

Yes, you can drive it. Ride quality will be compromised and it will ruin your tire if you drive it too long in that condition.

I placed the order for a replacement strut today from a local dealer, so I'll get it installed as soon as it comes in and will try to drive it minimally.

I ordered part # 33-50-7-856-901, are there any other related parts I need to order or would the strut itself suffice?

Thank you so much for your help, I really appreciate it.

Just strut itself is what you need.
The rest can be reused from the old one.

Turns out my passenger front and driver's rear are also leaking.

Here are pics of the front. Could this all be from an install error? I hardly drove the car 100 miles in total. The front passenger side didn't leak on the ground as the rear one did, the new shop noticed the front when they were replacing the rear one.

This is all a bit nauseating

If it happened after spring installation, yes.

They must've let the shaft spin a lot while loosen or tightening the top nut.

I've ordered a replacement front strut. You mentioned above that driving for prolonged periods could ruin the tire, but from your experience do you know how long before that happens? The leaky rear strut was replaced yesterday, but the front won't arrive and get installed for another 7-8 days likely.

7-8 days will be fine.
Try to minimize driving it, miles wise.

It never happen to me, but I've seen tires becomes uneven really bad because prolonged driving with bad shock too long.
I don't know how many miles, but the shock doesn't even have oil in it anymore.

Looks like the strut will be here Monday, thank god for UPS Express Saver, so it should be installed Tuesday. Then I'll align it and hope the new shop has done it correctly this time.

Thank you so much for your help!
