Hi all,
Thanks for your replies, and sorry for the extended delay. I wanted to fix as many issues as possible before writing anything new.
I wanted to address the clanging sound coming from the wheels/suspension (when I going down a bumpy road), and the control arm issue pointed out by iRage (OC).
I checked with two local mechanics, and the control arm was not deformed, but everything else was worn out.
Initially, we replaced both link rods, the outer tie rods, and the ball joint of the passender side lower control arm. (I am not sure there are upper control arms in Demio model). We only replaced passenger side control arm ball joint, for two reasons. First, After inspecting the vehicle, the mechanic confirmed that the ball joint on the driver's side is not yet worn out. Second, Suspension systems on the passenger side often experience premature wear due to their exposure to road edges, which are more prone to damage compared to the middle of the road. (Something I learnt recently).
Then we fine-tuned the wheel alignments. Steering wheel balancing was better, but I feld like something was still off. Resting positoin of the steering wheel was still a slightly tilted position.
After few test rides and few days, it became apparent that even the clanging sound was still there. And I had to go for a second round. This time a different garage.
In second round, we replaced driver side control arm ball joint, and both front shock absorber bushes.
Yet, after few rounds of test rides, clanging sound is still there. (This is not a metallic clanging sound, more like two rocks hit each other). Assume that I have addressed all the commonly replaceable components in the front suspension system. Kindly inform me if I have overlooked any item.
Mean time I have done some experiments with the steering system. I am hearing a slick ticking sound coming from within the dashboard whenever I attempt to turn the wheel, while the car remains stationary. Furthermore, when I swiftly turn the wheel, I notice a faint clanging sound, which is similar to the sound I tried to address earlier. Perhaps the sound is indeed originating from the steering system.
If you do not have any specific recommendations, my next course of action will be to inspect and repair the steering system.
Here are the prices for anyone who is interested:
Outer tie rod (pair) - LKR 8950
Lower control arm ball joint (each) - LKR 7000
Link Rods (pair) - LKR 7300
Front shock absorber bushes (pair) - LKR 5900
That is all for now. Please let me know if you have any suggestions as I am new to this context.
Thank you.
