Post the alignment report here. That might help someone figure out if there is something off, especially if you compare with a report from another car of same make and variant. Like I said earlier I don't believe there is anything like settling down of the alignment except when there has been a suspension overhaul. Even my crashed SX4 with deviated camber would give same readings Everytime without change.

Assuming alignment report shows all green, you should narrow down to the nature of the pull. And since you said you changed tie rods, I believe there is zero steering play.
1. If you hold steering straight and hard, does the vehicle still pull to a side? Then toe must be looked into and redone with steering perfectly centered. In Madhus they use a digital spirit level for the same and ensure steering is at 0.0 before adjusting toe. You can opt for toe to be at the inner limits, ie on positive side to enable better straight tracking.
2. If that's not an issue, does the vehicle pull to one side if you let the steering slightly loose or free? And when this pull happens does the steering also rotate to one side slightly?

Last question, was the steering or steering rack ever removed/replaced in your car?

Re: Wheel Alignment & Balancing

@Audioholic,

a left-pull issue is inherent in my Safari, and we cant go with keeping all values within the allowed values and still expect zero-pull. Madhu's guys have been able to set the alignment in a way to give a workable setup - no pull, no un-even tyre-wear. But this time it's still eluding.

the HPS has been kind of overhauled months back, again by the same mechanic who has worked on my Safari for many years now.

If this is the case that you can't go with prescribed values, then trial and error is the only solution. Like I said the focus on adjustment would be based on the nature of the pull if you are deviating from be values.

Mechanics are not always analytical when it comes to issues. If the rack has been touched, then let go of the steering on a level road and let the steering crawl. If the steering wheel automatically rotates slightly to one side and stops there, then the rack and column would be the culprit and not the alignment.

Re: Wheel Alignment & Balancing

In my Tata, I have always noticed there is always a slight left turned steering wheel when the car goes perfectly straight, if you take the base of the steering (Pic attached) as reference. If the steering is perfectly straight (Ridge is not visible), the car goes to the right.

Had this since the first day, thought will go away after third service wheel alignment, however, it only become worse. I can also see an improper camber set by the tata SVC, which I overlooked.

Any suggestions on a good wheel alignment center in Hyderabad?

2. Steering position when the car is perfectly straight.

When driving straight ahead with hand(s) temporarily off the steering wheel, does the vehicle pulls left or pulls right?

Yes, you need an alternative alignment shop as this Tata alignment job is not up to mark imho.

The vehicle moves straight, else I have to redo the alignment immediately. The problem is, when the vehicle moves straight, the steering is no longer centered, it is offset to left.

Does any outside wheel alignment shop have these specifications of the model? As they seemed to be programmed in the system model wise, and the operator selects the model from a list to extract the optimal set up.

If the Toe-in is within specified limits and tyre press equal at front, try adjusting the steering wheel. I see you have a 2021 Tata Punch; the ASS should have a steering puller to do the job.

Will try in next service. Which has become greater concern for me now is

TATA SVC has entered an incorrect odometer entry for my vehicle during third service. The vehicle was serviced at 12943 KM, whereas the entry for third free service has been made at 16127 KM, above accepted service schedule of 15000 KM. I wonder if this will this impact warranty of the vehicle.

The svc said they will take care of it if it comes to that, but they cannot correct it as the job sheet is closed. However, you can't trust TATA Svc can you.

This issue of steering wheel off centre to the left encountered is NOT alignment specifications (range) related but is more of a 'finishing' or 'detailing' in the finalised alignment readings, which Tata seems incapable of.

Your best bet should be an alternative competent (outside) wheel alignment shops which are hard to come by btw.

Are these alignment specifications varying model-wise? If so, my doubt is weather an outside alignment shop will have the specification for Punch? Else it will be again same issue.

Your issue of steering wheel off-centre to the left whislt tracking straight ahead on a straight road is NOT caused by the (Oem) alignment specification (range) as displayed in current alignment report.

Hence any third party independent alignment shop or any other Tata service centre/dealer offering either exactly similar or dissimilar alignment specification (range) in itself, will not automatically determine whether the steering wheel is on-centre or off-centre.

The off-centre steering wheel as encountered here IS caused by the (not so properly done) alignment angle values/numbers such as the finishing front left toes and front right toes ....... which any competent alignment tech (whether or not he is from Tata or independent shop) would be capable of rectifying it to achieve a status of steering wheel being on-centre.

An alignment specification (range) in itself has no role in achieving a desired on-centre steering wheel position.

Solution: seek out another competent alignment guy (other than your current Tata guy) to deliver you a steering wheel that is on-centre whislt tracking straight ahead, AND no phenomenon of vehicle pulling to either one side.

Yes. That's the next task. To spot a good alignment shop that resolves this issue.
