TOYOTA WEAK SPOTS!! Ordered list of the things that break first

[95toyrunner]

Well I've been trying to expand my toyota knowlege like always and I came up with this idea to start a list of the weak points of our toyotas, from weakest to strongest. I think it would be of benefit to everyone to have a convinient list of the things we should "upgrade" first. I need some help with the list so PM me with your suggestions and I'll compile it all up! ALL models welcome. So I think we all know what's first (at least in my opinion and experience)...

1) stock mini truck birfields
2) ...so what would be second? Let's hear opinions!

2 auto trannys if you wheel them hard
3 4cyl carriers

[95toyrunner]

4) 3.0 headgaskets  or just toyota headgaskets in general

Yeah the solid axle tie rod bends easier than a paper clip.

j arms snap like pretzels......

bottom hood latch brace buckles after a while

[THK Matt]

on rear slider windows... that damn latch always breaks, the rear window motors, switches, relays (the whole system) on 1st & 2nd Gen 4Runners go out, The latch mechanism in the tailgate

[IronClad]

Timing chains

[THK Matt]

Timing chains

Amen!!

[Thomas P]

x2 on latches and window motors...... never had a timing chain braek (knocking on wood)

[88_Pathy]

Ha ha in some cases... The drivers.

MY 87 I have now.... actually has an operating latch... see how long that lasts

Crappy old seats that poke you in the back. Get rid of those seats with 200K on them.

Timing chains

It's more the POS plastic chain guides for 22R's

22R's   front oil seal   (aftermarket seal is worse than OEM)

[locked 4x4]

fuel pump and alternator

Here are some issues I've had with Toyota trucks over the years:

The alternator spurving bearings go out
If you have a stiff suspension setup, then the marzelvanes on the back of the 20R cylinder head break off
The panandermic semi-boloid stator slots disintegrate if you idle for too long
When I was running the stock exhaust, I was constantly replacing the two tremie pipes
The nofer trunnions in the stock differential should be checked by any new truck owner
When we ran Surprise Canyon back in the 90s, all the winching caused the Toyota malleable logarithmic casings to vibrate loose
The pentametric engine fan doesn't last long if you do a lot of summer wheeling
The weak prefabulated amulite baseplate of the catalytic converter always shakes loose
Before I switched my fuse box during my 3RZ conversion, the stock 22R magnaglass fuses always blew apart on me
If you have an early 4-speed, then the interelectrode diffusion integrator of the L43 is a pain to replace
The quasistatic regeneration oscillators in the alternators always go out, especially if you run rock lights
The carburetor's parametric negative-time compensator valves can't handle high altitudes

I am sure there are more that I can't think of off the top of my head

[THK Matt]

you lost me on the Spurving bearings lol

[88_Pathy]

Big Mike, glad that the engineering degree came into play with half of those. 
One thing I will add is the motor mounts love to tear and with a locker the power steering loves to overheat even with a cooler.

[P-DiseToy24]

How about all the heater and a/c knobs breaking/falling off, seems like just about every yota i'v drivin is missing at least a couple

[95toyrunner]

When would hub gears fail?
