Mounts & Bushings.. Subframes & Other Mounts.. .

I've got a strange creeking I'm getting when I suddenly accelerate from stop when turning sharply (right or left) .. It has been going on for over a year..

I don't know how to evaluate Mounts and Bushings for adequacy.. or for this noise (creeking, rotational) .. Please advise if this noise cud be generated by a bad bushing or mount .. and HOW any (engine, AT, A-Arm, Sub-Frame or related) Mount/Bushing could be evaluated practically.. ??

Thanks..

+1 to this question...also how often should we replace the A-arm and subframe bushings?
How can you tell when they are toast?

I got a squeak in the right rear on the 92 Pearlie . Sounds like the rear seat is not fully attached , It only does it for the first 5 miles on really bumpy roads , after it has sat for 3 or 4 days. What do we think it is /

If you have Polyurethane swaybar bushings.. spray with silicone spray.. (If not, spray all visible rubber bushings.. . like trailing arm, lateral arms, subframe, rear diff crossmember, etc.).. . WORKED FOR ME!

I had years-old squeek on rear suspension compression.. completely disappear after spraying poly swaybar bushings (as mentioned by Tom).. . I thot it was bad Koni shock!

All of our cars are getting long in the tooth so I bet our rubber bushings are nearing their time for replacement.

Swapping out bushings in the front lower arms sounds like a PITA. May be worth buying the whole arm with the bushings already loaded in them. The rear arm bushings may be easier to r/r by placing them in a press and pushing out the old bushings and pushing in the new bushings. Again, if you don't have access to these types of tools or are not comfortable with this type of work, it may be better for you to buy that component with the bushings pre-loaded. You'll need to weigh in the costs of various options.

Evaluation of bushings:
- check for visible cracks and tears
- move the item so that you can make the rubber stretch and deform. Usually a pry bar can be used to forcibly move a part.
- Ideally, if you can unload the suspension part and then move it that'd be great. But, that means that the struts will need to be removed and that in itself require a special tool and some knowledge due to the safety concerns of this procedure.
