What does a crush spacer actually do? I know where it goes but I don't understand what it is there for?

a "crush spacer" is just a metal collar that goes in the hub between the two hub bearings. it is there so that when you tighten down your wheel nut only the two inner races of the two bearing will be sandwiched so the bearings wont bind.

Default Steering Problems!!

my steering doesnt seems to center itself...but when i put the car on a car stand it center itself perfectly...as far as i know my servo(KO2143) is not where the problem is as i've fitted it in my other kit(not tc3) and it center itself properly...i have also check all ballstud(RPM) to ensure there's no binding and also clean the steering rack with rubbing alcohol. my steering rack is also has lots of side freeplay(left to right movement about 3mm range)...so far this is the most sloppy steering rack that i've seen in kits that i've ever assembled(C4.1/TRF414/MR4TC/ALEX).....servo has no freeplay on it....by the way kit is newly built ..servo is also brand new....and also the tires on the TC3 is foam if this does help

Wiley, could of things to check...

1. Is your servo horn stripped...
2. Is your servo saver on the steering rack too loose or too tight
3. I would still check for stripped gears in the servo, even though it is new...

Thats were I would start....

HTH

Hi TigeRyan

Thanks for you reply..

1)servo horn not stripped....tried on 3 servo horn(2 associated 1 aftermarket Aluminium)

2)i've tried from loose till tight...but it's still the same...even tried to loosen and tightening the 2 nuts that hold the rack

3)i might look into this but i tried using the servo on other kit and it center itself properly

can anyone let me know by how much does your steering rack has side to side play...like mentioned earlier mine was about 3mm??is this normal??....

and also it just doesnt return to center after turning right ...turn left it centers nicely

i'm pretty much stumped by this problem....anyone else please help direct me where i could try to solve this...

When you are testing your servo put your car on the ground ready to run. Then try your test, turn left and turn right. What you are doing is putting more load on the servo because of the friction and weight of the car. It might be possible that the servo cannot handle the load for some reason.

Have you tried a different servo in your car?

thanks kraig

i'll try to get another servo to test...but i dont think KO2143 cant handle weight on a TC....and also it center properly after turning left ...only after right turn it doesnt center...so the servo is more than adequate for the application...but heck i'll just need to take out another servo to test the centering

anymore suggestion would be greatly appreciated

total of 3 servo has been mounted on the car to check the steering problem i'm having...servos are KO2143/Futaba9450/Sanwa VR(airtronics) all servo are digital and has metal gears....but i'm still having the same problem...tested on other cars using the abovementioned servos all were centering properly

this car is one of the greatest car ever produced with 5years of no change of layout cept for running changes...but it seems this FTTC3 gonna be the greatest nightmare for me ....i sincerely need all the help i could get in trying to figure out the centering problem...apart from the servo i have change all the ballends/ballcups/steering rack/clean the rack ballbearings.....thing that i have check for tightness or whether parts are scrubbing against each other are steering arm/servo saver

i'm gonna rebuilt the whole car against and while i'm at it , i really hope someone could guide me in any way to avoid this problem

thanks

Default just a thought

please check if the ball cap screw protrudes inside the steering rack, it might be hitting the bearings.

If you remove the servo, does the steering linkages move freely?
If so then its probably the servo.

Have you checked if you used the appropriate servo horn?

Did you replace the ball cups? or just using the stock ones?

Have you checked the servo saver and the way it is placed and mounted.

Sorry bro, that's the only thing I could think of, sounds a little crazy but those are the mistakes that I encounter before.

I have one other thought similiar to the last gent....

Make sure you have replaced any ball cups in the steering linkage with RPM ball cups they are thicker and may run on the chassis and catch and they will require a slight tap to get past that point, and depending on the angle it could only happen going one direction....

Just another thought...

HTH

hi lem2

currently still trying to sort out the problem...now am at work doing night shift and brought the car along to diassemble it later

1)steering moves freely when not connected to servo arms
2)replaced the ballcups to RPM...but change again to stock ballstud(new unused ones)...and back to new "RPM"
3)servo saver checked
