Hey Roger,
Well, I just had my truck out at Hollister Hills (northern
California - http://www.hollisterhills.com/)
this last weekend and man, It did great!
Especially for being mostly stock except for 31’s. I did have one concern though. When I would
hit a bump at any speed with the wheels sharply turned I would get a sound that
almost sounded like metal twisting. It wasn’t really a clunking noise but more
of metal on metal or twisting. Not sure what it is but if anyone has encountered
this same problem, please throw in your two cents.
Thanks, James.
Hi James;
The source of that noise is the steering stops on the
front end. You can either apply some
grease to them or replace the plastic end caps with parts from the dealer. Its a very common “problem” on the IFS Toyota
trucks (‘86-‘95 models). For more
information on this problem, see the following web page:

Hi Roger;
Well, I checked and the plastic caps are there, only they’re
worn through to the metal. I also looked for the zerk fitting shown on the
photo on the above page and I didn’t find it on my truck. In its place there is
a regular bolt filling that hole. Is the
fitting a modification that you did Roger?
If so could you give some information?
Thanks, James.
Hi James;
There are no grease fittings for the steering stops.
You have 3 choices for this common problem:
1. Do nothing and live
with the noise, it’s not really hurting anything (besides your ear drums:).
2. Buy new caps from
Toyota and replace every year or so (the stops cost about $5.00/ea. from
Toyota).
3. Put a blob of
grease on your finger and smear it over the end of the stop and the place on
the
steering knuckle where it hits. Repeat every oil change or
when it starts making noise again.

Hi Roger;
How wide are rear leaf springs for an 89-95 Toyota Pickup
4WD? Are they 2.3 inches wide? I was
under the impression that they were, but I am not entirely sure. Thanks, Landmonster.
Hi Landmonster;
All ‘79-‘95 mini-truck springs are 60mm or 2.36”
wide. For more spring dimensions, see
the following page, that David Moore has put together, with an excellent
collection of stock and lift spring dimensions:

Hi Roger,
Found your web site last tonight, thanks for posting the
great info! I have a 1993 Toyota pickup 2wd 22RE 5-Speed with 193,000 miles on
it. It runs great!
I was wondering if you might please be able to tell me how
to slow down the fast idle speed of my engine when the weather is cold. I never checked it with a tachometer, but I’d
say it idles at 2200+ RPM below 40F. I’d really like to lower that speed and
minimize engine wear. When it idles warm it’s fine. It’s been doing this since
before 101,000 miles when I bought it in 1999.
Also, I will be adjusting my valves again at 200,000 miles
and appreciate your posting the how-to and pictures. It helped jog my memory,
as it’s been 3+ years since I’ve done the job.
Thanks in advance for any help you might offer,

Hi Paul:
There is a detailed write-up on the 22R valve adjustment
procedure available on-line at the following web site:
http://www.off-road.com/toyota/tech/22rvalves/index.html
In the interest of brevity, I’ll not summarize the
procedure in this month’s Truck Tech column.
After doing that, I suggest you test and adjust the Throttle Position
Sensor (TPS) per the instructions on the page below:
http://www.4crawler.com/4x4/CheapTricks/TPS/index.shtml
Again, this was covered in detail in a recent Truck Tech
column, so I’ll not repeat that information.
Finally, once the TPS idle setting is established, you can set the
ignition timing by inserting a jumper wire into the timing check connector and
set the timing to 5 BTDC. I have photos
of the various locations of the timing check connectors that have been used of
the years on my page below:
http://www.4crawler.com/4x4/CheapTricks/index.shtml#TimingCheckConnector
Yours should be in the TCCS Diagnostic Connector as shown
on the page above. You can then turn
down the idle speed using the large screw on top of the throttle body. Note that this all affects the warmed up idle
speed, but its best to get that all set properly first. For the cold idle, you can check the various
cold idle temperature senders and the air valves that supply added air for faster
engine warm-up. As those components and
their operation have changed over the years that the 22RE engine has been in
service, I would recommend getting a copy of a Factory Service Manual (FSM) and
refer to that:

Hey Roger;
I have an 85 Toyota 4-runner. Ok, the last couple of weeks my clutch peddle
had been getting a lot of free play to the point where I couldn’t switch gears,
but it goes away after a while back to normal, do I need to adjust the peddle
bolt under the dash, or what?
Tell me, ASAP... please.
Bryce Perry
Hi Bryce;
There is not much of an adjustment there as far as I
know. But you might want to inspect the
bracket where the pedal is attached to the firewall. It is not uncommon for the sheet metal it is
attached to, to fatigue and crack. If
so, repair the damage and it should be good to go. It could also be a leaky clutch master
cylinder. If so, you may see a lot of
fluid leaking down the pedal. Rebuild or
replace the defective master cylinder if needed. If the clutch pedal bracket and master
cylinder are both OK, then check the clutch slave cylinder. It is located on the transmission bell
housing (passenger side, behind the starter).
If the slave cylinder is OK then it might be the throw out fork that may
be the problem. You would need to pull
the transmission back from the engine to fully inspect and repair that part.

Hi Roger;
I had a question about your turn signal modification on
your 4Runner (http://www.4crawler.com/4x4/CheapTricks/TurnSignal.shtml). Does it make the light blink any faster than
it does stock? I have heard that combing
the turn/mark lamps will result in a faster flash (exactly like the fast flash
you get when a bulb burns out).
Let me know and thank you in advance, Izeloz Mnemo.
Hi Izeloz;
I have had no problems in 6 years of running this setup;
it works just like normal. I made sure
to use the same dual-filament turn signal bulb (style 1157) as is used in the
rear turn signal, so the relay is seeing the same wattage filaments that it was
designed for. I think you can have the
type of problems if you make the turn signal relay flash the same filament as
the parking lights use, since they are a different wattage.
