Car shakes when hitting the gas.
Good morning,
Still working on my TL, I seem to be getting closer to how I want it. A few things to get done, but here is the next concern.
Long story short, when I'm not on the gas, car drives like the beauty she is. However, the moment you hit the accelerator (especially in faster speeds), the car, not the strering wheel, shakes left to right. I know I need rear wheel bearings, and a couple of motor mounts, but is there anything else that it could be?
Thoughts?

Yes and no. We have a slightly bent rim on our Terrain and it shakes the car like a MOFO when under hard acceleration. There is only a very light shake otherwise that isn't noticeable 75% of the time.

Personally, I think it's this. When I got my tires changed back in the summer, the one tire keeps going flat, No holes in it, no punctures or anything.

Fill a spray bottle with soapy water and spray it all over the tires; where you see the bubbles you have a leak. No sense in guessing on the cause until you know where the leaks are located.

A tire that keeps going flat can be from several things.
- hole in the tire
- leaking valve stem
- bad seal on the bead
- bend rim
- cracked rim
- dirty rim (causing the bead to not seat and seal)
I usually take the wheel of the car and take a bowl of water, add in some dish soap, and use a rag to wipe the tire and rim down. Usually something bubbles and points to the culprit.
For what its worth....our Terrain bent rim is not our leaky rim. We for sure have a leaky rim...2nd set of tires and still have one tire that drops 2-3psi a week.

I had a bent rim on my previous TL as well and that was true but it would happen regardless of acceleration and worse with acceleration. Bent rims are more gradual (and may even dissapear with speed) vs axles which comes immediately out of no where under hard acceleration. If it's the passenger axle, change the intermediate shaft as well!

The one thing I would say is, it's more intense at faster speeds.

If "only" under acceleration, the most likely culprit is the axles.
If "only" at higher speeds, it is more likely to be a tire or rim issue.
It "could" be worn bushings in the front suspension.
It is always possible it is a combo of more than one thing. This isn't something we can troubleshoot for you over the Internet. Start with rotating the tires to see if the behavior changes. Next get the tires road force balanced and have the shop check for any bent rims. If the behavior doesn't change with changes to the rims/tires, it for sure leads back to the axles and the more likely culprit.

similar problem when i bought mine. It turned out to be a combination of a sidewall bubble (on brand new Toyo Proxy 4s no less), a bent rim which i replaced with a wheelership replica, and slightly out-of-spec duralast CV axles. Tires (Conti DWS) and wheel replacement fixed ~95% of the issue.

Hey bud, I thank you for being so responding.
So I took a drive today, maybe just 2-3 miles, and I notice, when I'm at lower speeds and hitting the gas, it does not happen.
When I'm at higher speeds, and I hit the gas, it tends to happen. Again, doesn't seem to happen when the gas isn't touched.

Before I tossed the new Duralast axles in the trash, when I was driving my 2006 TL, if I initiated light acceleration from say 20 to 30 mph, I rarely felt any shaking, however, if I wanted to gradually accelerate from 60 to 70 mph, I felt quite a bit of shaking. The new APWI axles have made the shaking at all speeds a thing of the past.

When you say "higher speeds", can you be more specific?

Honestly I don't think you could of explained it better. I would honestly agree that this is identical to my scenario.

It sounds like that might be a good idea. I'll take this as an opportunity to plug this thread... https://acurazine.com/forums/third-g...5at-tl-980266/
