hey

i have a xv10 95 2.2L Front Wheel drive toyota camry, which seems to make a knock noise after i accelerate. This happens normally when i accelerate slowly and release the gas pedal.. The car has done about 100,000kms. I think i might know wat it might be...but im worried it might be more than that...

Thanks Guys

A good way to attack these problems is to start with the cheap fixes and work your way up, so filling your tank with 98 octane would be the first step to rule this out, setting you back an extra $15 or so for the full tank. But given its after you accelerate I doubt this is the problem. It could be an engine mount or transmission related... although knocking is usually associated with an engine related problem (albeit under load... such as acceleration... not after it)

it only seems to happen when i accelerate and release the gas pedal...and the so called "knock" sounds seems to be coming underneath the engine :huh: and btw yeah i have tried the Premium fuel i dont think its detonation coz the cars fine accelerating up the hill...

thanks for the help so far

Check to see if the engine moves much when idling, stuffed front engine mount sounds pretty safe bet at this stage.

i dont think the engine moves that much when idle...btw the car has been in an accident, i went to a mechanic before and he said he couldnt hear it, but i sure can...

You'd be surprised at how much an engine can shake on startup and idle, especially if it's cold and not running smooth.

Check all your engine mounts, suspension bushes and bolts are tight, also check your exhaust brackets as the bolts and brackets always break and come loose with your model Camry...

yep ur spot on abt the exhaust brackets...i got a loose one now makes an annoying vibrating sound when i go on higher revs.....SOOO ANNOYING...im gonna ask the mechanic to check the engine mounts i dont think suspension is a prob...btw i heard broken engine mounts can be a strain on the transmission....is that true? can it screw up my transmission if not will it screw up anythin??

thnks!

Well... you got the 4 banger... it sounds like the front mount has had it... had a similar problem also... more of a clunk noise when it changed gears (car sorta moves a tad when it changes gears).

The dogbone style mount's gone too... don't bother replacing that until you ask a mechanic on which mounts have had it.

I ended up replacing all the mounts (there's a front, rear, transmission and the top dogbone mount) I bought em all through Supercheap and Autobarn (Supercheap charges freight, Autobarn doesn't, so see how ya go). I think I ended up spendin close to 600 to buy them all and get replaced by a mechanic.

You can get the part numbers of Thu (96Camry) at Camcrew if you need any further info anyway... that's where I got my info from :)

No worries mate... we're all here to help.

I reckon that if it's gonna be any of the mounts, it'll be the front, and the top... but if left for too long, the other mounts take a bit of a beating, and will end up needing replacement at the end anyway. From what I've heard, mounts normally need replacing after like, 10 years anyway.

Yeah that's fair enough... I replaced the whole set on my last 5SFE engine around a year ago... costed around 600 fitted?? Can't remember... bought some parts from Autobarn, some from Supercheap Auto (same company they buy from... lol) Autobarn doesn't charge freight, but might cost a few bucks more, and Supercheap are cheaper, but charge freight. However, Supercheap will only charge freight per order, so might pay to get the whole lot in the one go.

      Front parking sensors

      We have a 2021 VX Prado with Toyota bullbar that is the doing same thing, the dealer did a patch under warranty which made no difference. The dealer now says they fixed it under warranty (by doing the patch) and there is nothing else they can do so if we want them to keep looking at it we will be paying for it. That is not our understanding of how warranty works and will be taking this matter further.

      Cruise Control Not Engaging

      Hi. My 2008 Rav 4 cruise control has not worked since I’ve owned it. When the on button on the stalk is pressed nothing happens, not green cruise dash light or anything. Previously, I’ve had a problem when the ABS, VSC and parking brake light all turned on but that was fixed by a brake light switch replacement. But the cruise still does not work. I’ve checked all the fuses and all are good. Is this a common issue and does anyone know why it’s happening. thanks

      2007 - Floor mat

      Hi. I have a nice 2007 Grande which is still in good nick, except for the drivers floor mat. Normally it wouldn't be a problem to replace the floor mat but because it has the word CAMRY embroidered into the floor mat, I would like to replace it with the same again. I'm feeling reasonably confident that a Toyota dealership would just laugh at a request for another factory one so my question is, is it even still possible to locate an embroidered floor mat for my 17 year old car? If so, where? Or is there a business that will replicate the original?

      Toyota Corolla 2012 zre152 4 speed automatransmission issue

      Hi Gary, I would suspect a clutch problem, like not fully disengaging. Maybe you aren't fully pushing it to the floor, or the system needs topping up or bleeding or both. Herb

      Toyota Corolla 2012 zre152 4 speed automatransmission issue

      Hi Toyota owners, I'm new to this forum registration. I need some advice or help as I have a shifting issue with my 2012 4 speed automatic transmission. It doesn't do it all the time but the gears don't shift smoothly specially 3 to 4 gear it just bangs in when I'm cruising and it happens more often when hot. Got full transmission serviced with Toyota genuine parts no metal shavings in pan. Changed ATF 3 times. Full major service done, 100000 KLM on car. Full synthetic oil with 98 Ron fuel. Throttle body cleaned twice. Maf sensor cleaned. New spark plugs. No engine codes. Great loss of power sometimes specially on hot days. Please help as no mechanic knows what the issue is. Thanks in advance.
