Question Sway Bar Diameter?

Where do you read measurement for front sway bar diameter when buying new bushings? My 2002 F150 4x4 S/Cab XLT bar diameter gives me 25.??mm roughly; Slightly over 1". Moog seems to only sell sway bar bushings starting at 27mm. Is that what I use or am I not supposed to measure the bar diameter? I see Energy Suspension sells 25mm bar bushings but I don't want that style for winter use.

I just measured the sway bar on my truck when I replaced mine (We have nearly identical one). I remember the new ones were pretty snug and I use lithium grease to help slide them in place. I went and just re-measured mine it is the same 25mm

Moog does offer a 25mm...it just doesn't come up for our truck...not sure why?

What are you seeing in difference that gives cause for concern for winter??

I had installed poly bushed rear lower control arms in my 05 mustang and they were great. I like to drive that car a couple of times in the winter during storage but not unless it's extremely cold so no salt gets to it. I took it out for a ride in -30 temp and on every bump it sounded like the rear suspension was tearing apart. I guess the supplied grease didn't like the cold temps.

I guess when its that cold, things just ride like a lumber wagon....I just don't expect that the ride is going to be very smooth and wouldn't necessarily contribute it to just the a poly bushing. I understand what your saying though

Oh no, the ride with the stock control arms is fine at cold temps as the rubber bushings still twist/flex. Even the poly didn't ride that bad. I think the poly bushings are hard as a rock at that temp so it's the bushing trying to turn in the sleeve that makes the exaggerated rubbing noise. Thanks for your interest.

I've had poly bushings forever and haven't really noticed a significant difference in ride quality when cold. Can be a bit squeakier though.

OK, so I used a couple of wrench's to measure the sway bar instead of a caliper. 1" doesn't fit, 1 1/16" fits, so I guess I order the 27MM bushings for a 1.06" bar. Problem solved, thanks for your help.
