Front Sway bar HELP

[Grabberblueguy77]

Hey everyone,


Looking for advice on an annoying issue. Here’s the situation:

• Car: 2013 Mustang V6 Convertible, 171k miles
• Problem: Front sway bar bushings have been shot for a while—thought it was struts at first
• Found out my sway bar is 33.3mm
• Ford doesn't sell bushings for this size
• Bought Energy Suspension 33mm poly bushings (was told slightly smaller was better to avoid play)
• Had them installed at Mustang Magic (Long Island)
• Squeaked worse than OEM bushings within a day
• Reinstalled with Formula 5 grease — quiet for 2 weeks, then squeak came back
• Sprayed silicone last week — helped temporarily, but squeak returned today
• Noise mainly coming from driver’s side bushing

Trying to avoid replacing the whole bar. My options/questions:

• Are there rubber bushings that fit a 33.3mm bar?
• Worth trying to re-grease with a needle and grease gun?
• Any other proven fixes without dropping big $$?

Appreciate any tips—thanks!

I'm not saying this could be your solution, but you may need to revert back to a rubber bushing, not Poly. Someone with more knowledge than me can chime in but i believe Poly bushings inherently create more NVH.

I'm not disagreeing with you. If I could have I would have bought the OEM 33.3 rubber bushing from Ford. Unfortunately I couldn't find any rubber bushings and definitely not ones that fit that diameter. So after speaking with energy suspension they suggested I go with the 33 mm slightly smaller than the diameter of the bar so that there's no play. The problem is I believe there's too much friction even though we over lubricated the bushings with formula 5 grease to prevent that.

I don't know how different the setups are between the different models, but maybe bushings like these would work better?

Pardon Our Interruption...

Are you sure its supposed to be 33.3mm? Just searching on RockAuto for a 2013 v6, it looks like they are 34mm:
