Body Mounts or The Joys of Owning a 20 Year Old 4runner

[seank]

I love my 4runner. I love that it's 20 years old. I love that it's a 3rd gen, the best gen hands down. I feel very fortunate that it's relatively rust free. I love that it was over engineered and the only thing the Toyota engineers didn't get 100% right are the lower ball joints. It's an awesome truck and I have greatly enjoyed what has turned out to be more restoration than modification.

Except for one thing.

Bolts of a sufficiently low grade that in the span of 20 years and 277,500 miles have degraded by fatigue, corrosion, other means, or a combination of things to the point where I am snapping heads off like I work at the Purdue plant. I have stopped keeping track of all the bolts I have snapped off. I have tried close to half dozen methods for removal of headless bolts, and succeeded not once.

Am I frustrated? Hell yes I am frustrated. Am I going to give up? Where would the fun be in that. Do I know what I am going to do to fix all these seized bolts? Not in the least. Did I use massive amounts of PB Blaster with multiple applications? Yes, please don't skip this part and recommend it.

So what is my current problem? Well, I went to install my 1" body lift this morning. I pulled trim, cleaned around and under carpet. I just about used up my current can of PB Blaster with the final application of who knows how many yesterday afternoon. And then I went to remove the drivers A-pillar mount (mount position 2). Not even the impact would budge it. I thought this strange and broke out the 3/8" breaker bar. No joy. 1/2" breaker bar and *pop* freaking A-pillar mount falls to the ground. I tried the rest of the mounts on the drivers side and they all came off no problem. Then on the passenger side *pop* goes the A-pillar. I'm guessing this was a result of the PO loving to snowboard without front mud flaps. While Colorado isn't the rust belt, they do still dump stuff on the roads I'm guessing especially in the mountains. But that's just speculation.

So anyway, the mounts look like the inside of that mountain in Mordor where Frodo threw the ring; all jagged stalagmites and stalactites where the tube is supposed to be. It's pretty cool actually, I'll grab some photos in the morning. But now I need new mounts and guess what, I can't find a good diagram with part numbers. I am fairly confident I need:

52203-35200
Cushion Sub-Assy, Cab Mounting, NO.2

and

52204-35110
Cushion Sub-Assy, Cab Mounting, NO.2 Lower

To the tune of about $54 per set, not including shipping.

What I am not sure about is if I need a tube, and if so what part number. What I've found are these:

Toyota Part No.: 90440-16018
TUBE

and

Toyota Part No.: 90440-16019
TUBE

And now that I think about it, I made need some of these washer plate things listed in the same section. Every part number can be found here, sans diagram:

1996 Toyota 4Runner Cab Mounting & Body Mounting

So my question to you, dear forums friends, is does anyone know the complete and correct list of part numbers needed to replace the A-pillar body mounts?

Thanks!

Not sure of the part #'s but since you mentioned restoration I wish I had replaced all of my body mounts when I did my body lift. Just because I was in there & would have been easy. That link you provided looks like it has everything. Those washers look way overpriced, I'd get them from the hardware store. There's also Poly Body mounts out there but I haven't researched them. 4Crawler.com has a lot of info on this.

Also you dont have to take the front bumper off to do the front 2 like all of the write ups on here say to. If you have a long enough socket extension you can get them from the engine bay. But you'll need another person to either hold the bolt or turn the nut from underneath.

I live in the salt belt & have snapped a few bolts but I've taken pretty good care of this truck by bringing it to the car wash a lot during the winters.
I try to replace every bolt with Grade 8 whether it needs that strength or not. They're cheaper at the hardware store than an OEM Grade 5 bolts.
Anti-Seize is my new best friend right now.

Impact wrench, the tool you don't know that you need. Especially with an older vehicle.

A good one

Yeah, I really should have just ordered the poly bushings when I ordered the body lift. Live and learn, or usually just live and groan. I'm going to contact Roger today and see what the lead time is, I need them real fast with the bumpers coming soon and the impending move from Denver to Vancouver. Fingers crossed I can get them next week.

WRT to removing the bumper, I appreciate the info. I think it's really good for people to know, but in my case it's currently a non issue :-D

Also, anti-seize, YES, I use a lot of that as well. I'm originally from the East coast where I always used it without even thinking, think it's saved my butt numerous times.

Preach it! I've had a Craftsman air-impact for as long as I can remember, but recently picked up a Dewalt 20v 700ft/lb impact for when I inevitably need to change a CV axle on the trail... the thing is amazing, haven't used air gun since.

I've got polys and with no bl for sale in the classifieds. You'd have them by Monday. Just a thought. Pm me if you're interested

Good tip. I got my 4crawler poly body mount bushings last week and plan on installing them the next free weekend I get.

But seriously though, that's some insane rust on those bolts. No amount of blaster is going to prevent that scale rust from turning into powder when you apply a small amount of twist to it.

That said, I too find myself griping about material quality on my 3rd gen sometimes. Then I look over at the odo and see 341k miles and realize that the fact the material in question even lasted this long is a miracle, regardless of it's condition. 277k in Colorado and being wheeled? That's... a lot.

My sincere apologies for using the wrong the 'due.

Yeah, I realize and agree that nothing I did ahead of time would changed the results. Just something that has be accounted for I suppose, like by ordering all new parts that come anywhere near whatever the project at hand may be. And 341k? Damn, that's awesome. For what it's worth, as the third owner I'm the first person to actually wheel this rig, the previous two only drove it on the highway. So that may account for why it's in as good as it is. It still feels like a restoration though.
