Hi everyone hope you’re well. I own a 2010 Lexus RX350 that is at 178,000 miles that has had a vibration under full acceleration since day 1 (160,000 miles).

Initially the vibration was only under full throttle, and would go away while cruising. This got worse overtime, and currently the car shudders and vibrates badly starting from 40 mph upward.
Upon diagnosis, I come to know that both driver and passenger side CV Axle boots are blown. The question is, is this vibration/shuddering only axle related or could it be something else? If I go for replacement CV axles, can anyone recommend a good affordable brand? Thank you all for your help and any helping comments are appreciated.

NOTE: There is no shuddering or vibration at idle, in any gear or changing in and out of gear.

 

First thing is don't drive your car until this is fixed a broken axle will do severe damage even to the point of destroying the transmission. Take your pick from the standard replacement list I've tried most of these brands haven't seen much if any difference.

I can't say for sure if your vibration is axle related but it could be either way they need to be replaced before you have catastrophic damage.

Be aware that aftermarket CV axles are always a crapshoot. You may get a good fit, or you may not. That goes for all vehicles, not just Lexus/Toyota.

 

I'm about to find out with our 2008 ES 350. Decided on Cardone new, rather than Cardone rebuilt. Another brand I'm hearing good results with is GXP. I usually make a stop over there and ask around because there are more DIY'ers over there. I rebuilt my entire 2008 ES350 suspension in 2022 and had no problem with stuff not coming off. All I did was wire brush all dirt and corrosion (Texas car, so none really), wd-40. let soak a few days. then come back and do the work. This is SOP for me.

At 178K miles, you probably have other things that need replaced down there depending on where and how you drive the car.
