Lubricate sway bar bushings

Should you lubricate sway bar bushings?

DIYers and even some pros always ask if they should lubricate sway bar bushings. It’s a good idea.  As sway bar bushingsthe vehicle encounters bumps and body weight shift, the sway bar rotates slightly in the bushings. Over time this wears out the bushings and creates noise. In some cases, a new bushing may make noise right way due to its tight contact with the sway bar.

What lubricants should you use to lubricate sway bar bushings?

Avoid all petroleum based lubricants as they can degrade the rubber material. That leaves two choices; a silicone based grease or dry Teflon spray. The advantage of silicone grease is that it tends to stay in place and not wash off.

Find dry Teflon lube at any hardware store.
