Low RPM front end shake

[shortbusondubs]

Looking for some advice. I have a 2007 4Runner sr5 4wd. 183k. The last week or so I’ve noticed that under a light load I have what feels like a front end shake at 20, 30, and 40 or so mph. It doesnt feel like a trans issue as I believe I’d feel that more through the rear of the vehicle. It feels Like I’m hitting rumblebstrips for a few seconds. I’ve got blown cv boots on both sides which are being addressed in the next few weeks. I’m just curious if anyone else has had any symptoms such as these and if so, what did you do to remedy them? Thanks in advance.

Theres a lot that it could be, you said it only happens under load which I take to mean that foot off of the gas means no rumble? Same while going those speeds and rev'd in neutral?

Does it do it all of the time or just coasting, accelerating, braking etc?

Also are you in 4wd or 2wd and does changing that cause it to go away?

2WD. I haven't tried changing it to 4 to try yet. And when I accelerate more the rumbling stops almost immediately.

What do your motor/trans mounts look like?

If they were shot it might give you those symptoms..when you give it gas the torque might be holding it tight.

Total shot in the dark but worth a quick look especially if they haven't been changed yet.
