Here's a post I found while looking in the Fj80 seciton. Hope it helps, Sean

Regarding the brakes:
These are large, heavy (3-tonne) vehicles. They are not "easy" on the front brakes if you are using the stock 80-Series pads. The solution is to use the 100-Series pads as most of us have done. You will easily get 30k, maybe 40k on a set of front pads. About the same with rear pads. This assumes normal use and good rotors.
Regarding the luxury amenities:
Air conditioning. Few problems here. We hear of the occasional leak and other isolated problems. I would say on a scale of 1 to 10 the A/C system is a 9 for reliability (10=No Failures, 1=Many failures.)
Power Seats. Few problems here. The only common problem is a plastic gear that can come off. Reliability scale=9. If you are a big guy you can get seat extenders from landtank. The leather on the driver seat can crack with age. Replacements are available or you can cheaply cover with cloth, or you can repair the panel.
Cruise Control. Very Few problems here. The CC actuator is not serviced and a new one is expensive. Reliability scale=9. There are some DIY "fixes" that a dealer wouldn't do but we have found these fixes will resolve the few problems that are reported.
Power Windows. Some common problems here; primarily with the driver window. Slow operation, poor electrical contacts, window coming out of frame. Reliability scale=7. Almost all of these issues are DIY fixes involving lubing the tracks, readjusting the actuator assembly, cleaning the electrical contacts, etc. Parts are available and not too spendy. If you go in to the electric switches, do the auto-up mod.
Moonroof (sunroof.) Some common problems here with leaks and wind noise. Both are easily fixed. The most common problem reported is water coming down the headliner. This is due to crud getting stuck in the drains and is an easy fix at no cost. Reliability scale=7 (mainly because a lot of people park under trees.) Those of us with no trees and no rain are clueless on this problem. The operation of the moonroof is rarely a problem. The mechanicals and the electrics are virtually foolproof. Reliability scale on this part would be a 9.
Fuel Injection.
The system is a superior design but like any engine, it sees a lot of use/abuse and must be maintained. Common issues (not problems) are dirty throttle body and the rare clogged/leaking fuel injector. Reliability scale on the entire system I would say is 8.5 There are a lot of pieces in the system. IAC, TPS, MAF, intake hose, injectors, fuel pump, fuel pressure regulator, fuel filter, fuel pump relay. We see a fair number of issues here but nothing out of the ordinary. There is a lot of wiring in the FI system and most of it goes through the EFI fuse. A wiring failure will blow this fuse and this will disable the vehicle. On the very few "tow it to the shop" stories that we hear; this blown EFI fuse is a likely culprit.
Computers.
There are several computers (ECM/ECU) in the 80-Series. There are very few reported failures with 1 exception. The ECM in the '93s is prone to failure and expensive to replace. Its a crapshoot on whether or not it will fail and when they fail the vehicle will continue to run but it throws codes. All other years have virtually no ECM problems and that includes the tranny ECM, the air bag computers, the diff-lock computers, and all other computers in the 80-series. Reliability scale=9 ('93 =6)
That covers the things that you mentioned. Now, I will raise the skirts and tell you of many known (to me) problems with the 80-Series. I won't elaborate on most of these but you can find more information by doing a search. Please read the summary at the end because I want to make a point.
PHH - There is a small hose that is difficult to access. It will fail with age and, like any coolant hose, the results can cause extensive damage if the engine is overheated. Inspect this hose (~$10) on your new purchase and replace it as PM and you'll be golden.
P0401 - The EGR system is problematic, esp. on the '96 & '97 models. Many of us have thrown this code and it can be frustrating to get it fixed. However, the repair cost is not bad (~$200) if you take it to a dealer and let them deal with it. This will not disable the vehicle and you can drive for months with a P0401.
Engine harness - The engine wiring harness passes close to the EGR valve and over time, the heat will melt wires giving indications of a fuel injection problem. You can be proactive and wrap this harness with good heat tape (~$20) and you may never have an issue. Most failures have not disabled the vehicle but the engine will run rough. If the failure shorts the EFI fuse then troubleshooting is a little more difficult.
Intake hose - There is a rubber intake hose that goes from the air cleaner assembly to the intake. This hose cracks with age. The vehicle will run poor but it is unlikely that this will disable the engine. The fix is a new hose ~$80.
Cooling system issues - The cooling system on the 80 will do an excellent job of keeping the engine temps at the design specs if it is in good condition. If it isn't, (like ANY vehicle) you can cause yourself a lot of problems. The solution is to baseline your used 80s cooling system (radiator, coolant, thermostat, hoses, rad cap, belts, etc.) and make sure the entire cooling system is operating at 100%. We have seen very few problems with the water pump.
Drive line issues - About the only thing we see here is the front axle service. The front knuckles should be properly lubricated at 60k mile intervals. This is not a difficult job but it is time consuming and messy. A proper front axle service will cost you about $300 (DIY) in parts and supplies. You will repack wheel bearings at this time, replace knuckle bearings, and repack the birfield joint (CV) during this service. You should repack front and rear wheel bearings at 30k mile intervals.
Starter issues - The Toyota starter is a simple device and is easy to R&R on the 80-Series. There are replaceable contacts and a copper plunger. They fail at ~90k miles and need to be rebuilt (~$25 parts). You should easily get 2 rebuilds which would mean you'll need a new starter around 300k miles. Not too shabby if you ask me.
Head Gasket issues - (Saved the worst for last) This is an enigma to many of us. We have seen poorly maintained vehicles approach (and exceed) 300k miles with the original HG. We have heard of HG failures in '97 (the newest) models at 50k miles. We have had original owners with impeccable maintenance that had a failed HG. We have had original owners with impeccable maintenance and ADDED SUPERCHARGER with the original HG. The statistics are all over the place and (my opinion) is that it's another crap shoot. Yours may last and it may fail tomorrow and it may have nothing to do with prior maintenance.
The good news is that the repair job is well documented (thanks to Dougie, Landtank, and others) and you can DIY in a long weekend and ~$500 in parts. Many of us would recommend that you do the HG as PM if you are concerned about it. Personally, I am watching mine like a hawk (aftermarket temp gauge) and at the first signs of impending failure, the HG will be replaced. I may also do it as a PM this spring but I said that last spring too... so I dunno. Mine has 165k on it with the original HG.
I think this about covers 90% of the things that we discuss in this forum and I want to make a point at this time: It is unlikely that your vehicle will "suffer" from all of these issues. Even if it does, you can do everything yourself and the costs are not that bad.
