Are they plastic or metal? I am at 104k and want to swap them out, but 55 bucks each is killing me when I can get the SKF bearing for >10 bucks all day.

What is the general consensus on just swapping the bearings?

My understanding is that it's possible. In fact, there was a guy who wanted to start rebuilding them and selling them with new bushings, but I'm not sure that ever went anywhere. Overall, it's just not my cup of tea. lol

My thought is if they are plastic, I wouldn’t as I think they would be compromised by already have ones pressed in. But if metal, pressing seems like a decent option.

I got bearings at NAPA for the ‘08, and had the mechanic press them in while doing the alternator... the first time.

REPLACE them asap due to your mileage because once the idler goes, it usually tears up the front cover and is EXPENSIVE to fix/replace. I have done three front covers in the past 7 months,

This is a little late, but the idlers are metal just like Gregg said. I just did the replacement and I’ll add to the diy thread when I get a chance. I put the idlers in a convection oven at 450 for about 90 seconds. Poured some water on the bearing to cool it slightly, turned it over and popped it out using a hammer and 24mm (I believe) socket on the inner race. The bearing OD is slightly larger than 27 mm, but it is pressed into a stop on the back side (can’t use a 27 mm). Removal is semi destructive as such but the bearing is replaced anyways. I did use the 27mm socket to tap the new one back into place (while the idlers was still warm/hot). Also put a little oil on the outer race and wiped it off (leaving a light film) before tapping in (went in fairly easy with a dead blow hammer). I’d say it’s 50/50 worth the cost of getting the complete pulley with bearing. I actually cracked a 10inch C-clamp trying a cold press out before coming up with the above solution on the fly.
