Hi all,

I'm usually pretty good with finding OEM part numbers, but this one has me stumped. I need the part number for the centering washers for the rear shocks. The ones that have the little raised lip that sits in the frame. I've had a terrible squeak from my driver side rear shock lately. I just took it apart and found out that the centering washer has been worn through in one spot, presumably because I am running LC shocks in the rear.

I couldn't find the part number anywhere, so I ordered a cheap shock from advance auto, assuming it would come with the washer. Nope... Now I need to return that also.

I'm sure I could get one from a junkyard, but I'd like a new corrosion free washer.

If anyone can help me out with this that would be great!

It sounds to me like you need more than just a washer. The stock setup is a metal- washer-rubber cushion-frame-metal washer-rubber cushion-metal washer sandwich. Going from top to bottom:

RETAINER, CUSHION, NO.2(FOR REAR SHOCK ABSORBER)
90948-02131

CUSHION, REAR SHOCK ABSORBER, NO.1
90948-01003

RETAINER, CUSHION, NO.1(FOR REAR SHOCK ABSORBER)
90948-02119

FRAME GOES HERE

CUSHION, REAR SHOCK ABSORBER, NO.2
90948-01045

RETAINER, CUSHION, NO.2(FOR REAR SHOCK ABSORBER)
90948-02131

If you do have all that, then I think the one you need to replace is:

RETAINER, CUSHION, NO.1(FOR REAR SHOCK ABSORBER)
90948-02119

Thanks so much!!! I couldn't find that part number anywhere.

That should be the only part I need. I'm running Land Cruiser shocks in the rear so I've got LC bushings, and I'm using grade 8 fender washers on the outside ends of the bushings because the 3rd gen washers are too small for the LC bushings, and the LC washers are $10 each...

Just to clarify though, the centering washer, 90948-02119 goes on the bottom side of the mount right? So that lip sticks up into the mount, and the bushing goes underneath. Like this


^ - nut
-- - washer (RETAINER, CUSHION, NO.2, 90948-02131)
[ ] - bushing
-- - mount
-- - centering washer (RETAINER, CUSHION, NO.1, 90948-02119)
[ ] - bushing
-- - washer (RETAINER, CUSHION, NO.2, 90948-02131)


Thanks again!

Yes, it comes directly beneath the frame mount with the cushion retainer's lip going inside the hole of the frame mount.

Awesome thanks! I thought so, just wanted confirmation that I haven't been running mine the wrong way for the last 40k miles.

Thinking about doing this and pairing them with ARB 906 springs.

How do you like the shocks?

What springs are you running?

Hey there, so is 90948-02119 the OEM 3rd Gen 4runner retaining washer and was it large enough to cover the bigger bushing of the LC shock?

thx!

I'm curious to know this, too...

Not actually sure what you 2 are asking . Your checking to see if this washer and the rear shock washer are the same?

No, the 4Runner cushion retainer is small compared to the LC80 shock bushing

The Tundra centering washer's flare is too large for the hole in the 4runner rear top shock mount pocket.

If the 4runner centering washer is too small for the tundra cushion then I will make a SS (or nylon) sleeve to go over the Tundra shock stud to act as an isolator. I'll measure the collapsed cushion stack to make sure the sleeve doesn't inhibit compression or movement

Unless there is a more elegant, factory-style solution

Ah. Gotcha.

If using the Land Cruiser shock and a drilled out mounting hole, then you want the 90948-02141, per Sonoran Steel as shown here. I found that link on this page.

However, within ~15k miles, the little lip in that washer that fits nicely into the drilled out frame wears flat. At least that has been my experience.

perhaps the drilling made the hole too big such that the washer is always moving around

No, the drilling results in a perfect fit for the landcruiser washer. The only thing I could've done incorrectly is perhaps too little compression of the bushings, allowing the washer to get out of position.
