Looking for replacement rear sway bar bushings. 2003 EX 4x4 V10 tow package. Stock bar. The OD of the bar where the bushing was located is 26mm. The Ford P/N on the bushings is 3c74-5484-ra. I've called several auto parts places and punched the # into Google - no returns. Sources, suggestions? Thanks.

 

Wow, an Excursion that came with a rear anti-roll bar from the factory.
When you say "tow package" what else did it come with - mirrors, brake controller,heavier springs?
Our 2003 Limited came stock with a trailer hitch and wiring for 7-way/4-way connectors/controller.
For your bushings, you could find some polyurethane bushings that will fit the factory brackets (or come with brackets) that have a smaller diameter hole.
Bore the holes out to 26mm, polyurethane machines similar to wood.

 

When I did my fronts, the ones I ordered came up as the larger size (and I didn't know any better at the time), so I ended up sending them back. Amazon is probably your best bet to find a 26mm bushing but a quick search didn't yield confident results. I think you're gonna have to take a swing at it and get something that's not necessarily a direct (OEM) replacement. I also tried rock auto, but searched an F-250 (MUCH wider selection) and came up with this:

Not sure if that'll work, but it says its for the rear 26MM sway bar.

Let us know how it goes!

 

^^ Thanks! I saw those on RA as well, then x-referenced them to a NAPA part which I will go see this morning. Issue is that there looks to be less rubber between the bar and the axle than the pieces I took off. I did find a thread on this "other Ford site" that there were/are 18, 26, and 30mm rear bars available from the factory - Sway Bar Sizes

 

Yep! The other option you might take a look at is the Hellwig bar.

 

I recommend the Hellwig bar, it is 30mm and comes with all polyurethane bushings.
It would provide added roll resistance, similar to stiffer leaf springs adding to load capacity.
The added roll resistance is great when towing in winds or winding roads.

 

For the rear Hellwig, did you have to drill out the shock mount brackets to accept the new U-bolts? I went to install one in my 2005, and that was my case. I ended up not installing it.

 

Well, I took the rear bar off as I am installing V/C springs from ATS. If I have to I'll get the 30mm bar from a F250. I called a few places and came up with the last superseded PN for the original 26mm bushing, 3C7Z-5493-RA, but it too looks to be NLA....and now that I have this "new" part # I see this has been covered in other FTE threads. Damn...

 

Were the bolt holes too small or the bracket holes too far apart?
Mine bolted right up, no mods.
Did you call Hellwig, maybe they sent the wrong U-bolts.
I think maybe the F250 changed in 2005, but the Excursion did not.

 

That's likely the issue. I ordered from Summit based on my vehicle.

 

Well, I ended up with a solution. NAPA PN 265-2158. It's a 1in ID split bushing, so close enough. The nose profile and width for the bracket is the same as stock. It's got more rubber on the back of it though, so I simply trimmed off the excess to match the dimension of the stock bushing. Greased, slipped onto bar, installed bracket, and done.

 

Thank You so very much for the part number from NAPA. I was going nuts trying to find something to work.

 

I managed to find the moog 1" PN k8653. Fits the front of an 81 F-250 as well.Fits the rear of the ex like a glove. Sorry just my 2 cents!!!
