Shock absorber LH and RH and bearing were ok and need not be replaced . They said if it needs replacement they would cover under warranty ( I hardly believe though)
The vehicle was ready for test drive.
Severe wobbling, vibration and front suspension noise is all gone.These were main problems noticed during long Mumbai Jaipur trip.
left side pulling and wobbling particularly at low speeds and at rear still there. These were before the trip also for few months. Wheel balancing and alignment is not solving this.
The diagnosis for these issues is worn out tyres. As the vehicle has clocked 66k on oem shoes, the above said problems will get solved apparently with new tyres.
I think changing tyres is must now.Also as almost full suspension setup is new, running it with old tyres would damage it. If the problem persists after change ,I will have to start a new chapter with M&M.
Seek opinion from the team whether such tyres can cause noticeable wobbling and pulling? Have I really driven too much on stock tyres?

Dear All,
Further update on above post:
Changing tyres was the first action required to further solve the problem of wobbling and pulling after the lower control arm, link stabilizers and engine mounting were replaced.
My search for tire brand did not take long as my sole choice was Michelins.
The only question was whether to spend so much right away as I wanted to change all 4 tires and my running may go down substantially due to change in job. Soon I convinced myself to take the plunge !
The dealer identification was also simple as I had earlier replaced my Swift tires to Michelin from Punjab Tyre Sole Vashi Navi Mumbai and they continued to appear on Michelin's web site as favorite dealer.
My search on google presented three options :
Michelin Primacy 4ST
Michelin Pilot Sport 4
Michelin Primacy SUV +
My requirement was low noise & vibrations,comfort & smoother drive and good dry braking. Rolling resistance,aquaplaning, sporty drive were not top priority. I thought ST4 was the best choice.
Things changed on visiting the dealer. The dealer presented Suv + tires and informed that ST4 and Pilot sport do not come in the size of 235/60/R18 which is the given size in my vehicle.
As per him , the tires are kind of bifurcated with ST4 being suitable for sedans, Pilot Sport for 5 seater SUVs like Creta, Seltos and SUV+ for bigger SUVs like XUV,Safari.
Though I was not fully convinced with the explanation but I was OK to fit an 'SUV' named tire in an SUV. The company must have engineered it accordingly!
Also, a quick peep into dealer's portal showed the size available in ST4 only in Ahmedabad. May be after launching SUV+ series, they discontinued this size from ST4.
Meanwhile,for info,ST5 series is going to come soon. They may have limited sizes initially but over the course of year many sizes would be added.
The last step was to finalize the price and I think I negotiated at a good price with 16875 INR per tire including Balancing and Wheel Alignment. I did not get anything for old pair.
Circling back quickly on the need for replacement. The OEM tires had driven 66k in 2.5 years . The tread depth had come down to 2.5-2.6 mm ( legal allowed 1.6 mm) and the tire wear indicators were in-line with the tread indicating the tread had depleted to the indicator level.
After the boring part was done, now was the time to get new shoes on.Hurray!
It took around 1 hr to get all 4 tires changed,balanced and Wheel alignment done.
To my dismay, one of the wheels needs a 60 gm balancing weight while others needed around 15gm each.The explanation was that RIMs do get damaged a bit due to bumps or pot holes and this is not a major concern.
The alignment was off . I do not remember the degree but it was enough for the service guy to bring my attention with the promise to see his workmanship in making it zero.
He did show his craft ( apologies for the unclear image).
Few pics below of the New tyres:
The week & year of manufacturing - all four tires are around 26,29th week of 2024.
The drive out from the shop was a great difference to what it was while going in.
The cabin was remarkably silent , the wobbling was gone and a quick dash at high speed with sudden braking proved the dry braking capacity was excellent.
I thought this is it. I have finally reached the end of hell. But something was telling me , it was not.
The thing I noticed all through the process of tire change and a little later at Fuel station while filling air was that neither my vehicle not the Adrenox app on phone ever gave the notification of air leakage or air filling as it used to do always !

Articulating the issue, when we fill air or remove it ,the typical scene with previous tires was that the turn indicators on vehicle would blink and one horn sound would come as well as the wheel on the vehicle info MID screen would blink with change in tire pressure. At the same time,adrenox app will give notifications. This falls under the Tyre fill assist system in TPMS.
None of this was happening now.
It is not that the vehicle screen is showing error or not showing TMPS at all. It is showing all four tires and the psi count . Adrenox is also doing it. Also a fill from 30 to 35 is showing but with lots of time leg and without the usual registry of air being filled and in increments almost similar to source device. Now it suddenly would jump to say 35 from showing 30.
In short, I feel my TMPS is now not sensitive and tyre fill assist system is not working. I think while driving, if psi drops due to puncture, it will not give warning.
Strangely,if sensors were bad , it would not show at all but I do not think sensors have gone bad.
I showed it to ASC which said we have done manual learning of sensors and it will work now.But it does not. The ASC also said , I have noticed that after tire change people feel this but it is not a problem.
I took care that while changing tires, the sensors are not damaged.
I seek help on this from bhpians as I dont know where and what to look for now.
Since new tire specs are same I do not think tire change is the cause . As manual learning is also done,I have run out of ideas now on solving this.
Before tire change, I used to love the functionality when my vehicle's fill assist system would almost always go at par with Nitrogen machine and I would feel satisfaction seeing the two settling at the chosen psi point.
I want that back !
