The primary purpose of struts and shocks is to "dampen" the unsprung weight of the wheel assembly to prevent bounce. In other words, shocks and struts stop the wheels from bouncing when you hit a bump.
Without shocks or struts, a wheel would bounce like a Basketball when you hit a bump, and the wheel wouldn't be in contact with the road very much of the time. That makes the vehicle unstable and difficult to control especially when you're going much over 15 MPH.
As opposed to shocks, struts also include suspension springs and bushings, so it depends on which part of a strut is going bad. If the springs are getting weak and the vehicle is "sagging", that's probably not too terribly unsafe, just an annoyance. If the bushings are shot, don't drive it.
In my opinion, it's not a good idea to drive without good struts, but that has to be your decision.
Struts and shocks have a life span of 50k miles.If your struts have started to leak,they need to be changed as soon as possible.
The shocks or if it has them, the struts, are worn out, and need to be replaced.
If they leak, break or stop dampening the ride
NO That depends on how the struts attach to the knuckle or control arm. On some front wheel drives an alignment is required.
sounds like your front struts need to be replaced
If struts need to be replace on a car it's evident by how noisy and bumpy the ride is. The cost to replace struts on a Toyota RAV4 is approximately $600.
Check for rusted brake parts, and also for partly seized bearing plates on the front struts, causing them to turn in a rough or jerky fashion. Sometimes the struts can be greased but often they need to be replaced.
The drive will need to be replaced.
Have a friend drive behind closely and watch for wheel bouncing.
They need to be replaced. There is no repair for them. Check E-Bay before the dealer. You can save a lot of $$$$.
Once struts fail, they have to be replaced. You will need a torx socket. I do not remember the size but but guys from almost any auto store can help you to find out. Make sure that you change them both.
before you change struts,check that all tire pressures are correct and the same.if tires are right then you need to change struts
