tug-tug-tug sa ilalim

**bonkph** · September 26th, 2008 09:07 PM

Mga Sirs, help naman. I have a 1year old Avanza, may naririnig akong tunog sa ilalim pero di ko alam kung saan galing, para siyang mahinang tunog ng drums na constant ang beat at sabay sa pagbilis at pagbagal ng takbo.

Actually mahina lang siya na hindi gaano maririnig kapag maingay ang kalsada. Medyo ramdam din ng kaunti, ramdam ko kasi 1 year ko na gamit itong car at iba talaga ang takbo nya ngayon.

Parang dumadaan ako sa kalsadang sementado na may mga gitling. Ano po kaya ito? Kelangan na ba ng checkup? Thanks

Try mu check mga bushings mo baka may metal to metal contact na.

Every time your car is up on jackstands for an oil change, you should perform at least a basic under chassis inspection. Check all exhaust system components for possible leaks or deterioration. Make sure all the hangers are intact and in good condition. Look for areas where the undercoating has fallen off or has been damaged. Remove any dirt, sand off any rust and recoat (paint) the area. Check all rubber bushings and dust boots for obvious deterioration. Pay attention to those bushings found at each end of front or rear sway bars, as well as those that hold the centre of the sway bar to the frame.

The bushings used on front and rear control arms are also potential problem areas. If bushings have shrunk or shredded, handling will suffer and in many cases the component will produce a lot of noise. Check engine and transmission mounts for looseness or cracking of rubber parts. A broken engine mount that allows the engine to rise up from its proper location can be more than an annoyance. In some cases it can make the throttle stick open.

Go ahead and check your under chassis. No one know's better than you if you inspect since noise are hard to point where it came from.

saan mismo yung tunog nanggagaling? sa front or rear area? pag malubak ba daan doon mo naririnig? baka naman yung 3rd row seats mo di properly folded or properly locked? could be your tools also...unless pang-ilalim nga problem.

Hindi kaya wasak ang bituka ng isa sa mga gulong mo. Para rin kasing yung nagyari sa akin noon buti na lang di ito tuluyang sumabog kahit mahigit isang buwan kong pinabayaan.

Yung kamag-anak ko na mahilig bumili ng mga guwapong imported used tires sa lansangan ganyan din ang nangyari, sabay pa ang dalawang gulong.

perhaps your tires, new that they are, are defective. "oblong" (out of round).
remove the wheel and rim from the car, and roll it on a flat surface. if it can not roll straight, but veers off to one side, it's oblong.

Buhayin ko lang po ulit itong thread na ito.

I think I have the same problem with our 2005 altis. I'm not the one who uses it, pero ako nagpapaayos. May kalatog or tug tug tug sa bandang likod when the car is moving even if the road is even. Shop (it's a reputable shop in QC) I brought it too wasn't able to isolate and fix the culprit.

Had the car serviced just before Christmas and after Christmas ko na siya nakuha.

Here's a list of things done to the car over the holidays.

All engine supports have been replaced, stabilizer link has been replaced, rear wheel hub bearing assembly has been replaced, even power steering pump kit has been replaced. I also asked the shop to check the CV Joint (last PMS service, CV Joint replacement was on the recommendation by a different shop) but they said they checked it and the even tested it with a different CV joint from another altis they were servicing pero hindi pa din daw nawala yung tunog.

Also note: when I had the car serviced during the first half of 2017, new KYB shock absorbers were put, and replaced all brake pads as well.
The wheels are also in good condition, and even newly balanced and aligned.

Any idea what could be making the noise?
