coupe07

i'm still on my 2nd rack. Problem is oredi here, juz dat i'm waiting for it to get unbearable b4 i change.

Its a heng suay thing. It may nvr happen at all. It may happen very fast. Y n how it happen, i can only relate it to heat.

Coupe: If its heat related, what sort of cooling mods like additional oil cooler (if required) or vented bonnet help?

coupe07

oil cooler has no relation to the steering rack...

vented bonnet may release some heat. Batt relocation may release some heat as well.

The heat i'm talking abt here is the heat generated by the engine that is trapped inside ur engine bay that may not escaped due to not enough ventilation. The steering rack may be heated or cooked that causes this problem. However it is juz an observation. May be the cause, may not be the cause....

Bro, was talking with the MM service mgr today, one of the topics was regarding the steering rack. Apparently they have located the cause of the problem, contrary to wad is spoken here, they identified the problem to be moisture, esp morning when the car has been sitting there the whole night. Tats y after warm-up, the problem will go away, coz the water has been evaporated.

Hope tat helps.

PS: I think I will be getting another steering rack from MM again, which will make this the 3rd too (my mileage is 70+k).

Is there any steering rack connector under the aircon piping? If MM says it is moisture related, I can only think of condensation dripping from the aircon pipe. Maybe should silicon any potential connector.

More speculation: maybe it really is connector problem, but overseas they only experience it at one point.. in Singapore, 90% humidity all year, we get corrosion in multiple points, so the quick-fix doesn't work?

thats good. but then if it occurs, a change of steering rack will still be needed t fix it? or have they fed back to Mazda Japan to solve it? or the only solution is to be forever changing rack.

Or even hard soldering to the connector on the rack might be a solution. Maybe coupe07 has tried it too. If thats the case, then somehow water is getting into the sensor.

As per wad he said, there is no safety issue, just dun drive like a madman for the first couple of mins will do. If u noticed, it disappears after the car is warmed up.

His solution was a special sealant of some sort but tat has to be coupled with a "new" model of the steering rack which he is checking whether my car has it or not, still awaiting his reply.

Some members here have had their steering racks so bad that it comes back during driving even after car has been running and warmed up. So this method to get around it won't work after some time.

Change the rack, it is worth it. Safety first....
That is the final solution!!

Bro m a Singaporean owner, my ride is 5 years old, 1st batch of 8.

Had the problem since 2nd year of ownership. The americans did highlight the wire harness and provided some solution. I did a bypass on the wires by soldering and to date it only happen in a blue moon. The connectivity is pretty much the culprit.

On the first-born cars (like mine) the connector is right below the rad vent tube. If the engine gets hot the next thing is the steering cutting out.

The slightest resistance in a connector will turn off the power assist, to prevent it turning at the wrong time. The problem is NOT the rack - the problem is the wiring.

just wonder what do you guys mean by steering racks? is it the steering gear which is list in japanparts? MAZDA 32-110 STEERING GEAR

zavhan

Yup, tats the steering rack which holds the torque sensor that controls the weight of ur steering wheel. On it u will c a connector that wil lead to another juz beside the coolant reservoir, most if not all connection/wire issue related to the power steering is somewhere along the line.

^ thanx for the info

Anyone who changed their steering rack, can consider to sell me the fck up one. I offer S$150. PM me if interested. Thanks.

CKZ

I will sell you mine not fully F up yet.. wait for a month or so. I indented a new one from Japan is coming soon.

rockerfella174

our problems are opposite than youres which i can see because these mostly occurs during cold starts pretty much after warm up ,the problem ceased to exist..

some had their rack felt like turning a stone while driving- which i would say very dangerous.

do you think it is still the wiring connectors?

Hi! I started this thread sometime back becos I was desperately looking for permanent solution to this steering problem. It's a lot of money if we need to rack the rack everytime it malfunction.

To date..I have tried a few solutions from the forum and none really works. Further to that, it can be really dangerous becos the steering will sometime jerk either direction will driving. I recently crashed my car becos of that. Dont know if it will do any good to highlight such unsafe driving experience to mazda. Pls advise.

have you tried cleaning your power steering connectors? this happen to me, condensation build up on the metal parts and corrodes them, thus not giving and signal (electronic PS)...right under your airbox is the connecter give pull it apart and give a good cleaning (electronic cleaner,canned air) then put em back together and you should be fine

It has been ages since I'm back here...
just revisiting this old thread about power steering failure.

I have my car now coming to 5 years, the steering issue surfaces around the 3rd.
For a good one year, the steering has the morning 'shake'...
and eventually the power steering died.
drove around 3 days without power steering.
power came back, but rarely the morning 'shake'
and til now, the shake only comes once in a blue moon without much issue.

so, for those who dont wanna spend tat money swapping out the whole rack, can pretty much try out 'my way'... leave it.

Rack links above; I would comment that replacing the Rack has *always* repaired the shaking problem; replacing/bypassing connectivity seems to provide only a temporary solution

Humidity could be a factor

My power steering light came out just now. I just shake all connectors from PCM to the last one on the PS rack. Problem solved.
