The top of the strut is connected to the vehicle body through the upper strut mount, in some cases called a bearing plate. This bearing plate allows the strut to pivot as the wheels are turned. It must be flexible enough to handle slight angle changes and dampen movement of the upper end of the strut. This mount or bearing plate transfers vehicle load to the strut and spring, making the upper mount/bearing plate the load carrier and the lower ball joint the follower.
I found this on the Monroe site.
there are a few causes for this, could be trailing arm bushings or any suspension part. check the upper strut plate it may be worn out. the strut is hooked to inside of tire, so if a upper strut plate is bad it will make tire loose. I just had a new strut plate put on, that was the problem. a bad wheel bearing will howl if bad enough. because a bearing on abs is very expensive to re place, check upper strut plate. the plate that is on top of strut in trunk. if the plate, it has to come off and be compressed to take off spring.
hydraulic fluid leaking from it, broken spring, broken/grinding bearing plate (some struts)
Since the strut bearing is part of the strut-coil spring assembly, the whole thing will have to come out and be disassembled. See "Related Questions" below for extensive information on these procedures.
the most common noise maker in the front of any of toyota's cars is the strut towers also called bearing plates. not the strut itself but the plate that the strut rod bolts through and is bolted to the body with three bolts
should b bolts in engine compartment and then 1 bolt on bottom of strut make sure to use spring compressors and u will probably need heat for lower bolt dont worry about the smoke there is a rubber bushing in there u get a new one with new strut
This would be on a front strut style of shock. The strut mount has to allow the spindle to turn and usually has a bearing to allow this. If it is dry or seizing you usually get stiff steering and some noise.
Worn strut or shock absorber? Worn strut bearing at top of strut? Loose suspension parts? Worn ball joint?
what is the bearing cpacity of 50 mm steel plate
A growl or rumble that changes pitch when you turn left or right would be a wheel bearing going bad. A bad strut would allow that corner of the car to bounce too much.
Although there is a snap ring retaining the bearing, you will need to take the strut to a mechanic and have the bearing pressed out. If you take out the three bolts on the top of the strut tower, and disconnect the ball joint at the bottom, you won't have to worry about throwing the alignment out.
Make sure it isn't the tire first. You will have to remove the strut, and have the bearing pressed out.
remove the 22mm bolt at the top that holds the strut to the car DO NOT REMOVE THE 19MM NUT ON THE STRUT ITSELF UNLESS YOU HAVE USED A SPRING COMPRESSOR TO RELIEVE TENSION OF THE SPRING
