Thread: Question about GTP suspension stock.

milage. go under the car and see whats up. check for play in the wheel. im guessing blown struts/strut mount if higher milage, or the lca's taking a dump.

Actually, the Grand Prixs have a pretty nice ride, since their so fat(heavy)

Im willing to bet the cars got 100k+ miles and has entirely stock suspension components.

Replace the struts and strut mounts, and check all the bushings to see if any are torn or rotted, then enjoy the ride.

How many miles on your Prix? How are the roads in your area?

These two things can factor into the suspension greatly. Another thing is to pull the wheels and look at the struts. If they have oily residue on them, they leaked and are shot. That's one 100% way to know if they are shot. They can also get bad w/o leaking. But if it's as bad as you say.. it kinda sounds like they will probably have leaked.

Take it to a shop and have them look at it if ur not 100%. Their feedback will point u in the right direction...........most of the time. Lol

Definitely sounds like worn strut mounts. I had a car that hit rough spots in the road HARD. I thought I could get by with replacing the struts. It rode almost exactly the same. I then replaced the strut mounts and it rode like a normal car.

Suspension components are wear items and need replaced every once in a while.

This is true, but stiff sidewalls wont make a car ride harsh if the suspension components are fresh and now blown.

I have had stiff sidewall tires with coilovers (on my Stealth) that didn't ride near as harsh as a car with blown strut mounts.

Lower control arm.

Your dad is wrong. Struts can be bad without leaking, and strut mounts just go bad with age.

Easy way to tell the struts, push down on the fender and see how it 'springs back' and how mushy it feels.

well, try and make it a habit to not hit bumps, last thing you need to do is destroy the car due to improper care. Try and avoid the bumps until you get it straightened out, dont need more damage than there already is.


Also, dont have a shop do suspension work, its so ridiculously easy, its not worth the labor charges.

Some people don't have the proper tools and/or experience to do suspension work. This could result in serious injury. If one is not confident in themselves, or their ability then I highly recommend letting a shop do the work. All we need is to have someone get injured because that rented set of spring compressors were not on the spring correctly.

I disagree. Tools are cheaper than the cost of the work.
Spring compressors are not hard at all to use.
If compressing the spring is the thing you're most worried about, you can take the old assembly off, bring that and new parts to pepboys or similar and have them rebuild it for $20.

You don't understand.

Not everybody has mechanical abilities. Having a shop do the work is less expensive than a hospital bill if you don't use the tools properly. I have seen where people have had broken ribs and cracked sternums from the spring compressor slipping off and the spring rocketing into their chest.

Its 5 total bolts to remove a strut.

And thats why I stated not everyone has the ability to work on a car. It may be easy to you and I, but seem like deciphering a Chinese novel to someone else. I've seen people fvck up a brake pad change before. I was astounded at the ability to mess up something so simple.

Also not everyone has a second car to take the strut assemblies somewhere to be disassembled. If one does not know what they are doing they could end up costing themselves even more money in the end.

A GTP will have a stiffer ride then a concord, it after all is a performance car, and the concord is made for old people to drive to church. =) If you are worried about the struts bounce each corner than stand back. If the car continues to bonce more than or two times your struts are worn. If you hear them clunk when you bounce then the upper mounts could be bad.

Just sayin....

The GTP is a "performance car" yes. It does not have a performance suspension though.
