2004 V70R....When driving in heavy rain I get a very rapid vibration on the front passenger side.

It is not dependent on engine speed or braking. I can put clutch in or rev engine and it does not affect the vibration and I can also brake with no affect unless I stop completely.

It is literally only when there is above a gentle rain with a good bit over water on the road.

I am guessing it has to be suspension related?! Any experience with similar out there? I am hoping it's not a bad strut. Car has 120K on the clock though:confused:....

What kind of wheels do you have? Do you have an aftermarket wheels?

Secondly, have you tried a different set of tires or wheels?

I doubt this is the problem, but check your tie rod joints... Also, get your wheels balanced.

Stock 17's and it is my second set of tires with same issue
Make sure all your suspension components are not broken... It shouldn't just vibrate in the wet, that's just odd... There's no good way to diagnose something like that besides driving the car..

This might be a crazy thought... But is it possible that your independent ABS is running? It could be causing one wheel to "vibrate" Maybe the rain triggers the TC. Turn off your anti-skid next time you're in the rain... It's far out there, but without being in the car that's the best thing I can come up with other than broken suspension/steering components.

Given your symptoms I doubt this, but possibly a bent wheel?

That would be the most obvious solution... But he said it only happens in the rain...?

If rubbing you would know...the rain squeal is more like a loud scream...
Not always. I never heard this "loud scream", it was always bad vibration.

I did not know that, I was just using my experience, thanks for letting me know. Maybe your vibration sound is loose exhaust brackets? But yeah mine scared the bleep outta me before I knew the cause it was really loud.

If you still have your ebd, remove it. Check your exhaust hangers as well. Check your fender liner on that passenger wheel? Maybe...something rubs when it all gets wet/heavy??

How do I turn off anti-skid?

I will check for anything close to drive shaft but it seems weird that the rain would be the only time something is clanging and vibrating.

Going to replace spring seat and see if that helps, I think it is past it's expected life span.....

the shocks are electronically controlled so it could be water is effecting the connection and altering the damping. I'd think you'd post a SUM code though...

I would not classify it in anyway as a "squeal", it's more of a clunk and definitely from front right. I will try the DSTC off since it is raining today. Thanks for all the input

My rain squeal was a vibration and an odd noise with visable rubbing on the prop shaft. Remove resonator and live a happier life. Oh and that stupid brace /support/uknown low hanging POS!

I had this same problem in the rain and it is the EBD. It sounded to me like it was coming from the climate control system (as it sounded almost like a metal fan rubbing against something). When I took my car in for service shortly after this it was a bent EBD, but just remove it because a new one is almost $250.
