Good day Tuners

I have a toyota corolla NZE121R-AEPDK; this is the 2002 1.5 1nfe Singpore version. I recently did full suspension work on the vehicle, new tyres, calipers, rotors, shocks, link, inner and outer velocity joint and the steering rack. I have since noticed after installing the rack, the steering is very stiff and not feeling as normal. There is also a clunking/popping noise at certain spots whilst turning, not specific spots but it happens sporadically. There is also a notice of a steering vibration and a rattling noise at speeds at around 90 -100kmph (during testing). The steering overall feels off. One last point it is the steering is not returning smoothly or fully to straight after a turn; it does return somewhat but not as smooth or responsive as before. I tried to lock the the steering today and it locked only at a 90 degree angle (see photo).


Any suggestions?

Best Regards and thank you for viewing

failed to mention. This is the electronic power steering rack system

Did u take it back to the mechanic to check it? Maybe the replacement one was not good

Also did u get the car realigned and cambered?

If power steering is hydraulic system then did they bleed the air out from the rack also power steering pumps can fail after a rack change
Electronic rack works with a motor . Motors go bad

You need to check back the mechanic that did the work of find a new one from what I hearing

i have a pretty good mechanic but he lives in Brazil Village if you want a link up inbox me.

have ah boss mechanic that i go to for all my rollas...have a ltouring and a 2004 model....recently did a full steering/suspension job for the ltouring and it runs like new...

he located in caroni savannah road...ash and vid auto...6653640

If I am not mistaken the electronic racks and box systems have to be recalibrated so the control module knows where is center and how much degrees u are turning so the electric motor will know how much to adjust the rack by.

I am not a pro on this but just the other day I was having this convo with someone on the topic. Scan tool is supposed to be involved for the recalibration process
