    I’m trying to replace my lower idler pulley (below the AC Compressor) on my 03 Tacoma. Ordered new pulley for $6 on rockauto from SKP, but didn’t come with any sleeve/bushing. I didn’t see one on the idler that was already on, but this isn’t making sense to me. Does anyone know what size the bushing between the idler and tensioner should be on this pulley, or is there even one? Don’t want to destroy the idler pulley I just purchased.

    Bushing? Or do you mean bearing? I'm surprised a new pulley came with no bearing. So you didn't see one on the one you took off? The bearing is easy to see, may just be covered in dirt, mine was completely covered.

    I just replaced mine a couple of weeks ago but I replaced just the bearing & not the pulley. 6301 is the size but for the 3.4L. Your profile says 2.4L so not sure if they are the same?

    The steel bushing/spacer that fits into the bearing is second from the right in the 88440B illustration. I go thru bearing on these pulleys so often that I carry several pulleys all set up ready to install on the Taco when I head out for some extended offroading. The deep mud/high water I routinely wheel thru is death to these low-hanging bearings with some lasting only a few weeks. The longest I have been able to get one to last is a full year. That particular Timken 6301 2RS sealed bearing was carefully disassembled, degreased, then re greased with super high grade Marine EP grease. I have only seen the steel bushing/spacer available with the entire OEM 8844004030 assembly. HTH

    EDIT: The 2 areas on the 1st Gen Taco where the engineers at Toyota could and should have done better are the LBJs and this low hanging idler pulley bearing. I have replaced it a dozen or more times thru the years. Just for reference, the bearing in my OEM Toyota pulley was an NGK Japan 6301-DU2/6301-DDU bearing. That NGK JAPAN bearing has proven to be one of the most durable for me in this application.

    Was referring to the bushing (to the right of the pulley in the green diagram). Looks like I should just get the entire OEM assembly.

    Is that diagram referring to the drive belt idler pulley or the AC Compressor idler pulley? Wasn't sure if there was a difference.
