Westwood bogeyed the short eighth and slipped to 14th alongside Padraig Harrington, who parred the first seven.
There was a dream start for first round leader Michael Thompson. He drove into the rough and just chopped out, but then sank his 170 yard third for a birdie that made him level par and only one behind.
Northern Ireland's 2010 winner McDowell remained two behind with a solid opening four, as did the big-hitting Colsaerts.
Woods, Furyk and Toms all bogeyed the 520 yard first - the third longest par four in US Open history - and when Westwood came back from another bogey at the ninth with back-to-back birdies he was joint eighth and only three behind at three over.
First he holed from 12 feet and then he hit his approach from the right-hand rough to five feet.
Woods paid the penalty for pulling his three wood opening shot into the edge of the rough, while Toms and Furyk both missed the green off good drives and could not get up and down.
McDowell parred the second and so was only one back, while Thompson would have been back in a share of top spot but for finding sand at the third and bogeying.
Before teeing off McDowell said: "At the US Open 'Moving Day' just means don't move back. I'd like to fast-forward and still be two behind going into the final round."
So far things were going better than that for the 32 year old.
Toms also bogeyed the third - and so did Woods by three-putting from just short of the green.
It left Furyk alone in front at level par and he needed to get up and down from sand on the second and from rough at the next, his chip hitting the flagstick at speed and stopping six feet away.
McDowell missed a 15 foot chance on the fourth, but was joint second, with Westwood seventh following pars at the 12th and 13th.
Goosen bogeyed the last but with a 69 was only four over and in with a real chance of a third title on Sunday.
“I played solid today,” he said. “Disappointing finish on the last, but I’m looking forward to the round tomorrow. The key is hitting fairways - par is a great score tomorrow.”
After taking three from the edge of the 17th green for par, the 38 year old rattled in a curling 40 foot birdie putt at the last to move to two over with a round to play.
