Strut assembly GABRIEL or Sachs

If u can see leaks then yes u need new struts

Also while going over speed breakers u can notice if the car doesnt level out immediately but goes up n down 2-3 times before settling then u have bad struts

I also put MK2 Scirocco sway bars on her car, front and rear, and with Sachs struts all the way around, it handled and rode fantastic.

Get good parts: original ride quality, not economy, and probably KYB or Gabriel (Monroe has long been a decent brand, but people tend to question their quality these days, especially here on Reddit).

I needed to replace my front end suspension and installed GABRIEL G57027 quick struts. I've had them for a few months with no issues. I'm not doing any off-road driving, mostly paved roads hauling family and large items. I've had good luck with this brand on my LeSabre as well.

Almost forgot Sachs, if you have a euro car they are also a great choice.

Monroe and Gabriel are pretty standard brands with decent quality.

The factory Sachs struts are also pretty good. Not sure if the M-Sport got different shocks from the regular sport, but all that's left anymore from Sachs are sport struts. Unfortunately for those of us without the sport package it makes shock replacement a pain, since their resting position is shorter than stock, and makes them shorter than the spring. I never want to do that repair ever again.

There are some cheaper models available from Monroe and Gabriel but I've used both on customer cars and been very unimpressed. They felt harsh immediately and were clunking within 10k miles.

Factory struts are now made by Sachs and didn't last.

I bought Sachs once and don't know if I was unlucky, but they seemed underfilled. Hit repetitive bumps and they would immediately fade. Tires would bounce like basketballs. I could hear the oil frothing in them.
