PROBLEMS IN RAIN

[BILLSOLARA]

While driving in the rain my 1999 Toyota Solara V6 has a problem.
The problem is that there is a Knocking noise/feeling under the car while driving over bumps. Also in the rain my engine/exhaust noise gets real loud. Now all this happens once the car gets harm an once i go over a puddle, the problem does go away after 10 seconds. Does anyone no why this happens an/or how to fix this problem?

It only happens when you drive through a puddle?

I'd say water is splashing somewhere it shouldn't be. Probably going away when the engine heat dries it out again.

I get that too, only when it's wet, right under the driver's seat. Makes you feel like the bracket is loose or something lol.

But like MCOJerry said, probably just some water getting in somewhere it's not supposed to be....hopefully.

HI to every one , im new at this site and im really amazed with how friendly every one is , and the help that you can get by just asking a simple question ,
my question is the same , sometimes when im driving on a certian speed i can feel a knocking under the car and at that time it wasn't raining , i want under the car so many times and i could not find the problem , it sound like its its a drive shaft and i know that the front drive only have a half shaft , untill know it happened to me 3 times . but hopefully i will grab it , best regards to all mike

It happens wth my car too..like a big bang under the car that I feel right on the driver seat..it's rare but it scare me everytime hehe

it must be "normal" if we all have this "problem"

this is all normal. i had this same problem/noise when i drove my car in the snow and rain. I took it to the lift and looked under when it was still wet, the rubber mounts that hold it, move easier when wet and thus makes it seem "loose". once it dries up, it wont make that thunk sound anymore, mine went away since it hasnt rained heavy or snowed much recently.
Nothing to be worried about at all.

The first time it happened to me I was almost crying... saying "SH** I fu*** my transmission!!"
Now it's warmer and all is working fine..except a bad smell when I push hard the car..smeeling like a fart..I will try to find what's the problem!!

Us Gen2 owners have a TSB for rotten egg smell when under similar conditions. Waiting to solve other issues, but emission components have 80k mile warranty coverage. I think the TSB just replaces the cat.
