Radiator Core Support Bushings Replacement

Can the rubber bushings under the radiator core support be replaced without removing the entire radiator core support from the vehicle? Mine have dried out and are starting to come apart and I would like to replace them. I looked under the truck, and it seems like I should be able to place a jack under each side of the core support and take the long bolt out from under the bottom, and then the bushing and shims should be able to slide out.

Has anybody ever done this?

Yes, they can be removed without removing the whole radiator core support. If you look at the LMC catalog, you can see how they go together. LMC Truck Parts - Page 22
Good luck. And I would recommend using the poly-urethane bushings.

Thanks, Grubbworm. Am I right that you can jack up the front of the support on each side just enough to replace them?

Once you get all the hardware out of the way, they are not that difficult to replace. As I recall, I just used a pry bar to give me enough clearance to slide the new ones in place. You may have to replace some of the parts, depending on how worn or rusty they are.

I have some pictures of when I did mine.

I had to replace both the top and bottom bushings, and the brackets for both sides. Got all the parts from Ford. I jacked up the support, and used a measured 2x4 to hold it up while I worked. Also had the truck in gear and parking brake set on flat ground.

What brand of poly-urethane bushings did you go with, Grubbworm?

Did you notice any difference over the stock rubber bushings?

The core support bolt is threaded through the top bushing(big one, is threaded in the center) and it is nutted on the top side of the core support. There should be some shims in there on each side. Be sure to get everything back in like it came out. I will be suprised if you can get the bolts out w/o any trouble. Especially the ones on the batery side.

Beofre you button everything back down take a look at how the hood sits as well as the gap between the hood and fenders. The core support is made to mov every which way to line that stuff up.

I used these; energysuspension.com | Welcome

Yes,. I do notice a difference over the rubber bushings. For me it seems like a slightly stiffer ride and a little better handling. My wife doesn't notice the difference between the rubber and poly, other than it rides better now. But, for both my wife and me it feels like it rides better than when it was new. If you are worried about the ride, then I would do the cab bushings in rubber, and the rest of them in poly. Personally, I like the way it rides with the poly. It rides like a truck should ride...Like a Truck, not a car.

I'll guess, because the bolt could be under the battery mount tray ? Isn't one of the bolts behind the vent canister ?

Looking at my '80 F-150, I would say that no, you do not have to remove the battery (batteries?) but it might be helpful.

Ok, you made me go look. All you need is a long extension, a deep socket and maybe a universal joint or wobble extension. Good luck, mine looked pretty rusty. I did that area with fluid film a short time ago.

Just make sure your ratchet doesn't hit the battery terminal...
