Push down on the vehicle 4-5 times. If it springs back up 3 times, the springs are worn. This test is not for McFerson struts.
Disconnect the batery cable from the battery while the vehicle is running, if it dies, you need a new alternator there, buddy.
No there is no way to lower a stock Acura Integra without buying new springs. Lowering the ride height of a vehicle will require many adaptations to the suspension, including new, shorter springs.
If the back of the vehicle is sagging, yes. If not... don't mess with the springs. Many shops will try to sell you what you don't need, and that's because many mechanics don't have any idea what things do. Springs support the vehicle, shocks dampen out harmonic action of the wheels when they hit a bump. Anyone who tries to make more out of shock absorbers simply doesn't understand the physics involved.
Tell us what symptoms the vehicle has, that will help us help you.
To replace the air springs on an 89 LSC, you will need to access the suspension components located in the rear of the vehicle. Start by supporting the vehicle securely with jack stands and removing the rear wheels. Then, detach the air lines and electrical connections from the air springs. Finally, remove the bolts securing the air springs to the suspension and replace them with the new air springs, making sure to reconnect the air lines and electrical connections.
To change the rear coil springs on a 1998 Buick LeSabre, start by safely lifting the vehicle and securing it on jack stands. Remove the rear wheels, then disconnect the shock absorbers and lower control arms to relieve tension on the springs. Use a spring compressor to safely compress the old springs, then remove them from the vehicle. Install the new springs by reversing the process, ensuring everything is properly torqued and reassembled before lowering the vehicle.
First, get new shocks and struts...on that vehicle, not entirely sure, but probably struts in front and back, no shocks. Check for coil springs in rear. If rear springs are coil, then struts. If rear springs are leaf, then shocks. While you're at the parts store, rent or borrow a coil spring compression tool. You'll need to compress the coil springs to remove/reinstall new struts. Other than the compression tool, standard garage mechanics tools will do the job.
If your calipers are leaking they need to be rebuilt or replaced. If the vehicle pulls to one side or the other when braking it could also indicate a problem with one of the calipers.
To change the rear springs on a car, first ensure the vehicle is parked on a flat surface and securely lifted with jack stands. Remove the rear wheels and then unbolt the shock absorbers and any other components obstructing access to the springs. Carefully compress the springs using a spring compressor, remove the old springs, and install the new ones. Reassemble the components in reverse order, ensuring everything is securely fastened before lowering the vehicle.
To convert a 2002 Oldsmobile Bravada from air springs to coil springs, you'll need to remove the air spring system, including the compressor and air lines. Replace the air springs with coil spring assemblies designed for the vehicle, ensuring they fit the existing suspension components. It's also advisable to install new shock absorbers suited for coil springs to maintain ride quality. Lastly, check alignment and adjust as necessary after the installation.
If nothing pumps out you need a new pump
A 'caliper' is the main body of the brake unit. ( it is NOT "on the tire") It carries the brake piston and mounts for the two disc pads. You may need new pads if they are worn , but unless your vehicle is quite old it's unlikely you need a new caliper. Get someone who knows about brakes to tell you.
