I'll be cruising at 105km/hr on my way to work, and suddenly, it's like I've hit the grooved pavement at the edge of the road. Souns like vrrrrrrump! only for a couple seconds, and then stops. Happens whiles cruise control is set or not, tow/haul on or not, never happens below 75km/hr. but not all the time, couple of seconds at a time. then it goes away, drive another kilometer, does it again, goes away

The other night it was worse. I thought the van was tripping over its own front wheels, but than yesterday, barely anything.
So here's the back-round info.
2003 awd lifted 215/85/16 tyres.
Just changed out the burnt gear oil in the front, swapped in 75/90 Lucas synthetic gl5. Though I don't thinks its fluid related as it happen before change.
New moog sway bar links and bushings
Any ideas?
Also, it reminds me of when a friend of mine sunk his 2011 jeep jk in 40 inches of water, the torque converter had water in it or something and he never changed the tranny fluid after. At highway speeds it did a very similar thing.
I'm gonna need to do a long haul soon, as my grandfather just passed away, so I have a 500km round trip coming up, and I don't want to break down halfway.
Thanks again.
