I attached a video of the noise

https://youtu.be/tpRz-8qMpb8

So there's a click in the rear driver's side. I thought it's the break pads at first I replaced them still there. Doesn't happen if I'm just cruising only under load. Can this be the CV axle going bad? There's no consistent clicking while driving

No one has an idea of what this noise may be?

I copied the whole link and the youtube id. Link is no good. For me at least.

If it's just audio you can use www.soundcloud.com too.

Oh **** ok let me make it public I made it public you can check again but I didn't have an issue with the link

If it were the front and you were turning Id say CV joint as that's what it sounds like. If it lost the boot and grease along the way, likely cvj. I find it odd for the rear to click but i have zero history and w your car. Some more details perhaps?

It's the rear end. It's a 07 is250 85k miles. I'm the second owner all Lexus maintenance history. It just started recently. Doesn't click on turns. Only under load if I accelerate fast or slam the breaks. And only from a stop. Not if I'm moving already. I thought it was the breaks moving around but I guess not I changed them and still the same thing

Check the pinion nut!!!!

If there are problems you will see metal in the oil in the form of shinny oil.

Ok thanks. So it might be the differential? And if unscrew the pinion but will oil leak out that I have to refill. I don't want to open it up and not be ready and end up having to fill it back up

You said; "Its the rear end".

I said; "check the pinion nut" NOT LOOSEN THE PINION NUT! IF YOU DO THAT, %$@# will hit the fan!!!

Point is; you don't know. So drain the fluid via the provided drain plug. If silver and shinny **maybe** it's the diff. If just dark, probably NOT the diff. They don't just click for no reason.

You do know to fill it with oil once drained, yes? You will need a pump and fluid!

So, if the oil is clean you could have some loose bolts, bad bushings, or perhaps and axle CV joint going bad.

I'm thinking CV boot I've had a bad differential before and its different. This is on the rear left by the wheel. I'm thinking the CV boot is going bad. The labor will be pretty anoying to take care of in LA 100 degree weather. Part is cheap. But before I order the part I will def check the nut thanks for the advice!

Check the link holding the rear sway bar. It may need to be tightened. I had a clicking noise when giving it gas from a stand still and that was the cause.

Thank you will check it!

Did you ever figure out what this was? Check out the U-tube video below. It is not a great step by step DIY video but kind of gives you an idea what is involved. One of the rear axles was making the clicking noise.


I have a 2007 IS250 RWD and during my last oil change at 98K, dealer told me both my rear CV boots are torn and splashing grease all over the place. Previous oil change at the same dealer at 95K, boots had no issues. Both boots ( 1 on each rear axle) getting damaged at the same time? I don't track and drive the car mostly freeways 90% of the time and the other 10% is all city driving. Lexus dealer quoted me $4,000 to replace both rear axles (rebuilt ones) with labor. $2,000 was what he quoted me for both axles. Can someone with more experience chime in and let me know if it is OK to drive like this for say about another 5K miles or so if it is only the boots that are leaking grease without major damage? Car drives and handles extremely smooth. No noises etc.

Thanks.

I actually just sold the car 2 days ago and got a brand new dodge Challenger. I hadn't figured the issue out but 20k miles later it never got worse
