Ooze @ steering knuckle



Hi Toby
Thanks for the response.
I was just curious about the ratios in relation to what difference it would
make as you say in the second part of your answer.
I heard this before but like most things over time it slips from memory
untill you mentioned it.
My stock tyres were only 265/70/15 so about 29.5 inches I think.
I now run 285/75/16 about 33 inches.
Its also auto which changes gear depending on revs/ speed/ and labour on the
engine, put simply of course.
So if I put the old wheels back on would it change gear at a lower speed
and would the ratios of the diffs be better and less strained and the
braking effiency would be increased and id get better mileage aswell..
Just curious as I would not change back I think the old ones looked way too
small and out of place for such a machine as the 80.
The colorado is just stoke with road tyres and is a good bit lower than the
80 but the steering is a lot heavier and of course its manual which is
different, but it does get to a higher speed quicker.
Its a lot quieter than the 80, no roar from the engine and when it is
switched off the engine dies very smothly unlike the 80 which gives a last
jolt of life.

The different stock ratios that came on the European 80s can be quite useful
if you have, for instance, replaced the 31" tyres on your '90 to '92 manual
80 (3.7 ratio diffs) with 35"s. Just fit a pair of 4.1 ratio diffs from an
automatic model and you're roughly back to stock gearing. Of course finding
them is another matter. Ring and pinion sets (the ring and pinion define the
ratio) are available separately, but they aren't exactly cheap (often
similar price to second hand diffs) and then you need to find someone who
knows what they are doing to fit them - this is not a job for your Yaris
If you have put taller tyres on your 80 this might explain why the Colorado
seemed more responsive. That or your iffy fuel pump ;-)

I've managed to source an 87K mile front axle from a '95 cruiser, the
question is, will it fit OK in a '94 cruiser?
Chas the answer will be on the bulkhead spec plates of both vehicles

In case you don't have a copy of the famous TLC FAQ, here is the
definitive answer to all the ratios.
(And JB, if the ratios are different between axles, then you will get
wind-up and transmission failure very quickly as the wheels at each
end of the truck will be revolving at different speeds).
==========Axle codes are never located on the axle housings themselves. In
trucks manufacturered after 1976, the axle codes are located on the
build plate which can be found inside the engine compartment. The
pinion (and sometimes the ring gear have the tooth counts (from which
the ratio can be calculated) stamped into them.
