Hi,

I have been doing a bit more research and if that rubber giubo fails Lexus only sells the total  Propshat and not just the bushing alone 😒 as far as i have been able to determine.

hi cosmin,

I will check the  ones on my car and see how they compare. I wouldn't know if this cracks would affect the drive train so i will leave that to someone more knowledgable

Hi Brens, do you ever sort that out? I think I'm having the same issue at the moment. 

hi Cross95,

no i havent been able to get it resolved , i have been to a few garages/tyre centers  ( non Lexus ) and while they acknowledge "something is there" they can'nt pin point it , so iam just living with it at the moment.

whats more annoying is that i  have a 2008 Avensis that drives without any issues and sails along.

Someday when i can afford it i will drop it into a Lexus dealer, as a matter of interest what model/year/mileage do you have ?

hi colin ,

thanks for the info unfortunately  its definitely an issue internal to the diff itself 🫣 and will need to be replaced or fixed

hi all.

I'am looking for some help/guidance as I'am just back from my mechanic and we have diagnosed the rear diff as the cause of the rumbling/vibration felt when driving the car.

When the car was up on the lift and  spinning either wheel  while placing my hand on either wheel bearing I could feel nothing however when i placed my hand on the diff casing there was a definite vibration  from it .

we checked the fluid and it was nice and clean, so my questions are:

1. has anyone else expierenced this and what was the cure

2. is it a common issue ?

3. whats the best way to repair it ??

thanks in advance

Brendan

hi all

thanks fro the help. It's been ongoing for a while and i put it down to old tyres so i was hoping that new tyres would cure the problem but no joy. ther is no wobble at speed or under braking  and at lower speeds ( sub 50kph) its not an issue but is consistent  when up at 100-120kph, it really does feel like somewhere in the drivetrain/chassis something is askew.

I have read the link as poitned out by colinbarker and some of it is similar to my case so i need to contact my Lexus dealer and see if it apples or not.

Thanks once again

Hi all.

I have a 2014 gs300h that is having a very odd sensation when driving. The best way I can describe it as an engine vibration/wobble  when driving. It feels like a pulley wobble and only occurs when driving.

The sensation is not transmitted to the steering at all but it's felt through the chassis, I have had the tracking done as well as a new set of Tyres to no avail.

There is a pulley to the right as you look at the engine bay that has a very little bit of play in it but I don't know if it's related. As a matter of interest what does that pulley drive?

I also noticed the heatshield is also loose put seems from what I have read is a design feature rather than an issue

This is driving me nuts at the moment so any help greatly appreciated.

god iam getting fed up of this problem. 

brief update:

moved coils from 1,2,3 cyl to 4,5,6, and vice versa

removed shielding from the wires  going to cyl 1 coil pack  to see if there was any damage ( non found )

removed and cleaned the 2 Earth points on the head.

ran car all day yesterday without issue but i dont trust that its fixed 

so is the possible fix one of the above I dont know , but it may just work for you.

well another update

cleaning the injector connections has made no difference  but what i noticed is that the car runs fine from cold but once you turn it of and on again thats when the misfire occurs. I then let the car go cold and then ran it until it was hot with Torque pro running ( O2 sensors b1s1 b2s1b and b1s2 been monitored)  all was fine until i shutdown the car and left it for a few minutes. 

Once restarted after a couple of seconds there was no output form sensor B2S1 . verified this a couple of time so looks like a bad 02 sensor , have one on order so will see how it goes. sadly after this its going to be the scrap keep as i have just doubled the value of the car  so far ha ha .

Cant understand how the B2S1 sensor is causing a misfire on cyl 1, a bad B1S1 faulty sensor makes sense but not the B2S1 can anyone enlighten me  ??

thanks for looking

I've seen this before. It is could be caused by a sensor leaking oil, and the oil travelling along the wiring loom to the injector connectors. Or someone spilling oil on the loom during an oil change.

hi thanks for the reply and will see if i can find the source of the oil leak.

just a quick work in progress update.

I decided to check the resistances of the injectors and all within range of 13.4 -> 13.7 ohms. what i did discover was that injectors 1, 2 & 4  had oil in the electrical connectors see attached pictures. so having cleared out the oil and using electrical contact cleaner there is a marked improvement in the idle and so far no issues with the rough running. may be early days but will keep this thread updated as I have read lots of people having the same problems but never a solution been published. 

Injector 1 was by far the worst for the oil soakage and maybe this contributed to the misfire always been reported on cyl 1.   however i couldn't see how the oil is getting into the connectors  and wondering as anyone seen this  behavior ?

Maybe use the search function on this forum with 'P0301'?

It throws up lots of threads...

hi PCM,

thanks for that , i have checked the forums  and the Web quiet deeply and have been unable to resolve the issues hence why i posted.

Hi all,

got a problem on my 2003 Is200  automatic. when it gets up to temp it runs really rough and shows a flashing cel  and P0301. this is a misfire on cyl 1. I have replaced the coil pack and all six spark plugs without success. It has also recorded a P0701 ( system too lean on bank 1 )

O2 volts bank 1 sensor 1  = 0.965

O2 volts bank 1 sensor 2 = 0.03v

O2 volts bank 2 sensor 1 = 0.32v

Using android and Torque Pro

there is no visible sign of any wiring damage  and  i desperately looking on what else it could be. any help would be greatly appreciated

thank in advance

hi all

Today I replaced the 3 belts on my 2001 IS200 and ended up ringing the nut holding on the pulley for the Air-con belt aagghhh  . I have 2 questions

1 whats the part number of a new pulley

2. whats the part number of the nut that holds it in. ( or even what size nut is required as I'am sure I may have some in the shed but dont want to take it off as I need the car. )

thanks in advance
