Torque binding when turning a sharp corner

[johnnyapollo]

Could be a few things - I experienced something similar when the TOD speed sensors went out on mine (the FWD was bascially disabled so it was pulling load during turns instead of driving the front wheels). What you're describing could also be bad CV joint(s) from my past experience with Hondas.

The wheel bearing are going bad too. Could bad wheel bearings lead to bad CV joints?

[Joe_Black]

It's common for short-wheelbase vehicles to do this, and with only 90" the VX is firmly in that category. My Trooper RS did the same thing.

If you've got worn out steering/suspension components the added stress will make it more apparent.

Mine has done this since 5k miles (when purchaced)

I wouldn't say that bad bearings leads to CV joint wear. The bad bearings could certainly give you the symptoms you describe.

Bad CVs usually show up as a noise issue long before it gets bad enough to 'feel'. Clicking during coasting usually means the inner CVs are bad. Clicking during turning usually means the outer CVs are bad. Have you checked your CV boots? If you're not lifted & your boots aren't cracked or split & you don't hear any clicking noises (changing with speed) then your CVs probably aren't bad.

Maybe try to adjust the steering lockout bolt so you can't turn as sharp? No idea otherwise.

Is your tTOD check light on?

Cuz if it it, then your rear and front speed sensors that are located on the TOD itself have gone bad, or dirty connectors, or broken wire, pretty much what JohnnyAPollo said. But if not, then I don't know.

After the post the other day, I was driving home and the TOD "CHECK" light began flashing at me. The display also showed no lights to the front wheels, which usually there is at least one. After about 5 minutes, it all went back to normal.
So is this indicative of having a bad speed sensor?

TOD Speed Sensors
Are these the same "Wheel Speed Sensors" noted in the shop manual?

[johnnyapollo]

If I'm not mistaken the wheel speed sensors are at each wheel and feedback to the TOD ECU to determine when "slippage" is occuring - the TOD compensates by adjusting more power to front (back is always at "full"). The TOD speed sensors that went out on mine are both on the TOD unit itself - one in front and one behind the transfer case - these measure the speed the internal gears are running and also feedback to the TOD ECU so that it can adjust power to front.

Are you talking about the VSS?
There is no listing of 'TOD speed sensor' in the shop manual. Of course a search on TOD brings up about 1000 results......

I'm pretty sure that the answer to that is 'no'. There are Wheel Speed Sensors at the wheels, but they are used for the ABS system. The TOD speed sensor is located on the prop shafts, if I recall correctly. It is closer to the tranny than the wheels.

[johnnyapollo]

Makes sense.

I've located the Front and Rear Speed sensors.
4B2-4 in the shop manual.
But I cannot find a part number in the 'part list' for them.
We don't have an official local dealership. Where else can I look?

It sounds to me like what Johnny Apollo and other's have had including me (bad speed sensors)...

I just posted earlier today my transmission and t/c odessey. If I were you, I would check the wiring leading to these sensors first they get really close to the exhaust pipes.

I had a major transmission failure but I also had the symptom of what the manual calls "tight corner braking". This felt like a binding to me too... I lived with this for abount 6 months. I also had a "check TOD" light. Without out a code reader (special one from Isuzu) you are SOL. A dealer will read the code for around $85. I never got to the dealer to diagnose, I just swapped out a transmission and transfer case and the problem went away.

The front and rear sensor's are on the "Transfer case". These sensors are approx. $235 a piece, from Isuzu. In my travels on the net looking for a transmission, I found lots of transfer cases for the Trooper 2 99-2001 and VX 99-2001(these are interchangable and mirror image of themselves). I found one for $125.00 + $25 shipping and it had both sensors! They (transfer cases) ranged in price from $75-$350. That trims the cost from $470 to $150, plus you get a transfer case core in return to use for parts or exchange if you ever trash your present transfer case

The rear sensor is pretty easy to replace the one at the front is on top of the TC in a tight area. I did a straight r&r on trans and tc which entailed dropping the rear crossmembers and front and rear propellar shafts. Access to these places would be easy then. Try car-parts.com and follow the prompts and see whats out there. Dealers charge a lot to replace these, but its really easy especially if you have little hands.


Good lucK
