Hi,
Recently, my car front tyres inside portion keep flatten / reducing / eating (don't know what's that called?). Some say this reflected Upper and Lower Arms problem.

Any idea?

Tyre wear is the word youre looking for. It could be your wheel control arm, but could be other factors also such as worn suspension arm, tyre balancing problem, etc. You may want to get your car checked to see which part is causing the tyre wear problem.

TS,
What vehicle are you driving?

If its a conventional MacPherson strut front setup without any camber adjustment option, its possibly the lower suspension/control arm that's out.

could be so many things..... anything affecting your suspension geometry could be worn....

can also be your driving habit or the tyre itself

(btw middle wear... usually over inflated)

It's quite common actually to have the front tires inner side tread worn out say 10-20% faster. Is your car lowered? If so then this will be more pronounced. This is more about wheel alignment actually which is a bit much negative camber and/or toe out. So what you need to do is do wheel alignment first, try to dial in a bit of toe in, that will help reduce the inner side wear.

I'm super appreciate your replies, guys!

Actually:
1) I realized that issue last December, suddenly inner part Botak (1 1/2 year tyres usage).

2) Tyres were setup or aligned during replacement.

3) next service then, my guys told me inner portion worn quick abnormal, probably "Arms" are not functioning well anymore. Suggested to replace.

4) due to high price, RM4K - RM5K, he suggested optional way to controlling that issue by shift the 4 tyres to get the balance time to time.

I'm here to get more advices from you to make up my mind soon.

** Toyota Innova about 10yrs.

ohh wait inner as in towards the middle of the car? not middle of tyre? oops, not pressure then.... didnt know the upper/lower arms cost so much...

It's inner part, not the center or outside

Hmm normally suspension arms are very strong and would not cause too much uneven tire wear unless the car had been in accident before that somehow impact or bend the arms, or had hit severe potholes. But I'm not familiar with Innova so I cannot confirm if the arms are prone to problems. Your mechanic is correct to suggest rotating the tires, from front to back and left to right to try even out the wear. If your tires are symmetric tread pattern then you can also switch inside out (dismantle the tires from the rims and then reinstalled in the opposite orientation).

I too suffers from uneven tyre wear on my front left tyre. Its the outer part thou...

The steering pulling one side as well (pulling to the left), and i have done almost 10x alignment, balancing, rotating tyres etc but still happening.

The front left suspension area also produce a sound whenever im accelerate, slowing down or turn the steering. Kruk kruk sound...

Pls advice.

p/s: To TS, sorry to hijack ur thread, but i believe our situation quite similiar.

There's no probably "arms"... it's either your guy know what he is doing and the exact problem or he doesn't and just guessing.

He should be able to tell you exactly the problem, show the defective part to you and give recommendation on what to change to solve the problem permanently.

So far I've not come across any suspension problem where the defect can't be confirmed visually.
If one of the rubber bushes is old, you can see signs of cracking or tear in it. If loose nuts and bolts, then even easier to fix.

I assume your last dec alignment is done right.
When is the last time you check/change the bushing? Check also tie rod? Steering is straight at 12oclock? Jack the car up, give a few yank, is it got a lot of movement?

You can always go to another workshop for 2nd opinion, since the price quoted is so high.

you should go to a reputable shop and get it checked... or u can diy check... just jack up and try shack the tyre right and left, up and down, and push in and out.... it can tell you alot

Which means NOT ABOUT THE ARMS?
BRO. KL People Kesian LA, everywhere potholes ,can't avoid woh...
So, in my case with your opinion, ritating/shifting tyres is the solution?


He is ensured that Arms issue 😮 but he said will not solved that issue 100% 😢
Bush and Nuts that you mentioned from ARMS?


Alignment seems Ok.
What is tie rod?
Go to another shop for opinions is an good idea


So if loosing means the ARMS issue?

no... could be so many things... many components involved here .... if you dont know how to check, just bring the car to a reputable mech

I also stay in KL la, which IMHO pretty much smooth most of the time and not many potholes. Note that I used to live in another country & city where the driving condition and roads were way much worse than in KL so to me I consider KL plain sailing, a piece of cake to drive! And I'm always driving a lowered sedan too and yet not having much issues with suspension nor tire wear.

Anyway, if your uneven wear is quite severe then rotating the tires is not the real solution but just a work around to prolong the tire life. Actually when you do alignment, you should watch carefully the readings/measurements so you know if they're normal or abnormal.

Rechecking in another shop to get second opinion is a good idea.

Try to get a 2nd opinion from another shop.

4-5k sounds really cut-throat for a lower arm replacement.i just bought a front set of new lower arms for my RN1 H.Stream and its just RM170 p/side for OEM or RM240 p/side for ori Honda. Labor was about rm90 but it was incl other stuff.

Bro. I just wanna say, you are a kind man to the nation, haaaa... Ok. I supposed to consider road is milky smooth in KL 😂

Btw, I'll do once more tyres rotating and see how? Then, as well as check out with another workshop to get optional opinion!


4-5k for upper and lower arms (original) and workmanship for 250. Though, this is too high to maintain an Innova, crazy!

Btw, I really really wish to understand (or shall say ensure) that it wasn't ARMS issue! So, what else (cheap parts) should I consider to replace other than alignment?

Do much appreciated dear all!

There are many parts to the entire suspension system. Which arms? Upper control arm, lower control arm ?.. also some mechanic can't really name car parts properly and simply use a generic term.

How can it be he's sure it's the arm but not 100% sure it will solve the issue.
Plus at 4-5k .... I can get custom made shocks/spring for front and rear at that price.

Better get a 2nd and 3rd opinion.

He did mentioned Lower Arm. But better go for a set.
Yup. I'll definitely visit another shop soon! Thanks!

Yes for the mean time just do the rotation first while looking for 2nd opinion. For lower arm price, that 4-5k is damn expensive leh for just an Innova. Try give a call to Wing Hin Auto to get the true pricing, they are authorized distributor of Toyota parts.

In that case it's most likely just the rubber bushes of the arm.
Don't know how complicated Innova lower arms are, but normally you can just replace the bush and not the entire arm.

Appreciate! Can get Wing Him Auto contact online?

If really the Bushes, then save a lot ya!

Their phone is 92218867, located in Jalan Loke Yew, KL. You can just google to double check if still correct.

Pinpoint the problem first before call them. They are selling parts only, not a workshop.

Many thanks!

Which means, go to workshop to ensure the problem first?
