I have used Monroe Quick Struts before, they performed well.

Man what a difference these made. Super easy install and fast shipping. Price on here was the best at the time (99$each). Great deal.

My car is 14 years old with about 80K, so it was time for new front struts. With all the review for different car people and mechanics. Monroe struts was what I wanted to go with. My car rides much smoother and install was a breeze! The price I got them for was unbelievably low. These are the true quality Monroe sensor-track complete strut assembly. Advance Auto sells these struts also so I compared the part numbers just incase Amazon's search was a bit off (it was spot on!) Things to note when installing...1.Ride height might be slightly higher ( clearly stated on the yellow tag.) Although my car is level since putting them on.2. When removing the knuckle bolts hit the center of the knuckle with a hammer. The shockwave will help loosen the bolts (bottom bolt comes out first usually.3. Have the camber (alignment) checked so you won't wear out your tires overtime.

Great shocks, but this purchase is making me rethink online auto parts.While I ordered the correct "Quick-Strut Complete Strut Assembly", I received different parts in my order. I received "Econo-Matic Complete Strut Assembly" instead of the ordered "Quick-Strut Complete Strut Assembly." The "Econo-Matic" that was sent is a lesser quality part and has a price point of about half of that of the "Quick-Strut." The scary thing was that the box showed the correct part number, and the parts look very similar. So, I had the best-part box and the cheap-part in the box. Amazon of course did what they always do and I got my money back no problem. They did tell me the parts come from Monroe, so unless Monroe is running a scam, it must have been a mistake.That said, I bought two Quick-Strut Complete Strut Assembly kits at a local auto parts store (for an arm and a leg) and the struts are awesome. I gained about about 1-2 inches or ride height and they perform great. At first the parts are very stiff and will ride very high for a few days, but should settle and perform as advertised.Amazon Buyer beware!

Installed front and rear quick struts on my 99 grand prix coupe myself. You need jack and jack stands, penetrating oil (not necessary but it helps a LOT), torque wrench, 1/2 inch impact gun, 21mm impact deep socket, 15mm socket, and a hammer and small punch.After you jack the car up and secure it with jack stands, remove the tire and take some penetrating oil and oil the two large bolts holding the strut to the knuckle. Then take your 21mm deep impact socket and place on impact gun and take the nut off. You may need an 18mm open end wrench to hold the other side. After you take both nuts off, turn the nuts around and place them back on the bolt. The bolt will not come out by hand so this is where the hammer and punch come in. You don't want to hit the bolt itself. That is why you must put the nut back on and hit that. The bolt won't come all the way out since you had the nut on so take the nut off and use a punch to knock it the rest of the way out. Your punch may get stuck in hole where the bolt was so you may need to move the strut and knuckle to get it out.After both bolts are out, take a 15mm and take off the nuts at the top of the strut tower. Have a jack under the lower control arm to support it so it won't drop far and damage the ball joint. Take a hammer a knock the old strut out off the knuckle and it should come out.When putting the new one in you may need to put the bottom of the strut in the knuckle first, put one bolt through and jack it up to line the top studs in their holes. That is what I had to do but your situation may be different. Either way you will need to play around with it before it goes in. After its in, put the bolts back in and tighten them down. The torque specs on my car is 90 ft lbs for both bolts that go into the steering knuckle and 30 ft lbs for the 3 nuts on the top. Your torque specs may be different so check online for your specs. If you don't have a torque wrench then you need to use a breaker bar and get the 2 bolts as tight as possible. It will be very difficult. I have an impact and even that took about 2 minutes per bolt to draw the bolts all the way in. The nuts on top don't have to be as tight. After everything is tighten down, you are done. Put your tire back on and drop the car. Torque the wheel lugs to 100 ft lbs (again check your cars specs to make sure).If you are changing the rear struts (which I also did), then the procedure is the same. The only difference is you are dealing with a tighter space when trying to remove the bolts from the top struts. You also need remove the rear sway bar end link nut. The nut is 15mm. There is also a 5/8 nut on the back that you will need a wrench to hold when you put the nut back on the shaft link. Trust me, its very easy. If you do one strut, the rest will be a piece of cake. You probably will need an alignment when you're done.My car rides brand new again and it don't sag in the back anymore. I also have new lower control arms and front wheel bearings so that helps too.A few things I want to point out. If you don't have an impact gun you can use a breaker bar to get the large bolts loose. It will be very difficult if not impossible depending on how bad the bolts are rusted. You also may need to replace those bolts if they are really rusty. If you can't get them loose with a breaker bar, find a longer steel pipe that you can put on the end of the breaker bar to loosen it. Also having a second person makes this job that much easier.As stated my car is a 99 grand prix coupe. These struts work on quite a few gm front wheel drive cars so make sure you read the directions carefully. There may be other steps involved for your particular job. Expect this job to take about 2 hours (if you are using an impact and have a second person it may go a little quicker) to do the front and 2 1/2 hours or so for the rears.It may seem intimidating at first but its easy. This was my first time doing this and know that if you take it to a shop it may run you $1000 or more. Have fun and most importantly stay safe.
