Hi all,

I have this AWD RX330 and I noticed that when I coast and then accelerate there is a single jerk as the gear just banged in or something, aside from that there are no check engine light or VSC on. The transmission aside from this occasional jerk performs superbly (no slipping or delays or noise of any kind) I have done a tranny oil change early last year. This single jerk has always been there since I imported the car.

I some times feel that this maybe coming from the transfer case, maybe the transfer chain/belt has a slack during coasting and when you accelerate the slack tightens suddenly and causes the jerk. or does auto tranny clutch disengaged when a car is coasting? This is just a theory. I have gone online to check and discovered that most car make his this particular issue.

Can any of the auto gurus offer a remedy to this?
Pls am not in Lagos.

usually signs of impending gearbox failure/troubles...........
its gonna get worse, and by then the damage would be irreversible, take it to a reputable auto shop n get it scanned and sorted out. you may be fortunate and a simple fluid change will resolve the problem. when last did u replace the differential and axle fluids?
contact gauzz, he is among the good ones

Did you change the strianer as well or you just did a drain and refill. Did you run any scan?

Do you hear a thud from the rear under side of the car?
I feel its a differential or the bushings. If you're in Abuja contact

Its NOT a transmission issue. A lot of RXs have that slight shudder or thud when theres sudden acceleration and then sudden release of throttle pedal, while some have it during light dab at the throttle during coasting.

Yeah it sounds from under the car towards the back.
I am currently in Warri.

I am inclined to agree with you on the differential or seating idea, do you have any suggestions on how I can go about fixing it?

Your technician should jack ALL the wheels up, start inspecting the propeller shaft and joints, the propeller bolts and bushings. He should also check the differential bushings and bolts. Then also re-tighten the rear beams.
It's normal for these bushings to wear out after long usage due to wear and tear.

Thanks man, will do as you advised.

YEah, i probablly didnt read the post well,
it may be a differential issue, though my money is on the propeller shaft, some cars have zerk fittings tru which you can grease the shaft, its a common problem on the 4th gen 4runner, he cud also check the differential fluid and replace if necessary

Tot i was the only one experiencing this on my Lexus Rx330. Happens once in awhile, initially i thought it was a loose engine sitting but from my little research it might have to do with a failing center support bearing for the drive shaft . Am also located in warri & would love to know how you get to resolve yours.

Normal thing even mine experiences such once a while but, latest development, just below the lid of the glove box, I saw new cracks appearing

I've decided to just turn a blind eye to the cracks on my dash, the interior color of mine is black so it slightly helps in masking the cracks.

however if the crack deteriorate and becomes unpleasant to the eyes will consult you guys for options.

by the way I noticed my speaker is not as sharp as before both in FM or disc mode. Suspecting a torn speaker but am skeptical about doing a change till I can get someone who really knows about car audio systems.

New speaker na 5k, changed one 2months ago, having my dashboard re-wrapped next week. The guy did a poor job and has agreed to redo it. Also visited my mechanic who checked my drive shaft bearing, re-tightened some screws and also confirmed there's a bit of allowance with the drive shaft as designed which leads to that thud sound some times when it engages the axle/back differential. Confirmed it from anoda Lexus RX330 owner at the workshop.

Chairman I hail oooo,
pls do you still experience this thump sound?
why am asking is cos, given the fact that you are in a position to fix your car issue yourself and this is currently manifesting in your car (albert once in a while) is this something you feel is not worth the effort or was the fix a temporary solution or is there no fix to it?

I just want to get your opinion if this is something I should live with or make a effort to fix.

My fear in changing the speaker is getting capable hands to do the job, by the way what prompted you to change the speaker and how did you identify which speaker is bad?

In my case it is difficult to pinpoint which speaker is giving me the distorted sound, even when I tried isolating each speaker (via the POS (driver, rear, front, etc nub) don't know if all the speaker can be faulty at once or there is another issue causing the bad sound production.

Had the door lining removed and the speakers inspected found one a bit torn, had it replaced. Has a USB like connection Simply disconnect old one and fix the new one.
