Hi everyone,
I want to share my 2012 Wagon-R K series steering issue here, if anyone faced similar issue and have a fix, kindly help me. My Wagon R had a perfect, feather light steering wheel which always automatically returned to center on its own after taking a 'U' turn, all this changed after I changed the lower arms at M.A.S.S.
Sometime in 2019 I took my Wagon R to Mohan Chandra wheel alignment center (It is a very famous Wheel Alignment center and tyre shop in Hyderabad and are known for their genuine work for the past 30+ years) as part of routine maintenance. I was told that there is a 1 degree deviation in Right side lower arm, and it needs to be replaced. Apparently, for bigger cars like Fortuner, Innova, Qualis, Safari, etc, they use jack to straighten it, but for smaller cars, replacement of lower arm is only the solution. The worn out / out of shape front right tyre is reason for the same, as per them. ODO reading was around 43,000 kms then.
In few days time, I took my Wagon R to our regular Maruti authorised service centre, Varun Motors, Begumpet, behind shoppers stop. I was getting all my periodic maintenance services done from this dealership ever since we bought the car. During 2019 annual service, I asked my SA to change the defective lower arm, he told if lower arms are changed in pair, then it would be effective, otherwise one side will wear out faster and one would wear out slowly, and wear out tyres unevenly, I was convinced by his explanation and got both of them changed. Here starts the problem, the steering felt very heavy during the delivery. I questioned my SA the reason for heavy steering, he told "since tyres were worn out due to driving on damaged lower arm, and after replacement of lower arms, the steering will naturally feel heavy, after you change the tyres, the steering will become light again". I was convinced with his explanation and left.
Fast forward to 2020, most of the time our Wagon R was idle due to covid related lockdowns and restrictions, we did not use the car much. But got the regular yearly service done. As we did not use the car much, we did not change the tyres either and did not ask the service center about the stiffness in the steering during annual maintenance.
In 2021, we started using the car regularly, so I changed the out of shape, irregularly worn-out stock JK Ultimas to Yokohama Earth 1 tyres of the same size and specifications. 145/80/R13, along with wheel alignment and wheel balancing. Despite changing the tyres the stiffness has not gone. I have an OBD-2 scanner, hooked up to OBD port and checked for any EPS related errors, it did not show anything, even on the instrument cluster there is no EPS warning. So EPS issue is ruled out.
I gave for yearly service again in 2021 and they also did the 50 K kms service, the ODO was at 50,300 kms during the service. This time my regular and known SA was transferred to some other branch and has moved from service department to true value. I spoke to him on phone and he directed me to his friend, another senior SA at Varun motors, Begumpet. He did a good job on couple of other issues I had with the car and sorted almost all of them, except for this heavy steering wheel. I asked him solution for this and he said since the lower arms are fairly new (~7k kms old), they will become loose and smooth after some wear and tear. I was not convinced as I already covered 7 K kms, but did not have any option and returned home. The other option he gave me is to replace the steering rack. But there were no symptoms related to it, like any sound or vibrations coming from the rack. Only the steering wheel while trying to steer is on a heavier side.
Now in 2022 the MASS representative called for our regular service, our Wagon R current ODO is around 55,000 kms, it did just 5k kms after the last year's service, but the steering wheel heaviness is still present, the steering wheel doesn't return to perfect center after taking a 'U' turn. The fun of driving an EPS car is gone as we are used to only hydraulic power steering vehicles in the past. The car feels on par with Innova's hydraulic power steering, but nowhere close to Maruti's EPS.
P.S: I got my front suspension thoroughly checked by an FNG and MASS for any leaks in shock-absorbers, worn out bushes, tie rod ends, ball joints, any play in drive shafts, stabiliser bar, wheel bearings, and all other components. Every component is visually okay according to them.
Kindly suggest what might be the issue and what should I ask for when I go for this year's annual service.
