737 taxiing slightly sideways....?!
When I taxi behind a 737 it's clear that the plane taxis slightly sideways.
Meaning : the fuselage isn't centered with the center-taxiline.
Particulary funny when lining up behind one taking off.
Anybody knows the reason ?

There's no mention of this in any tech manuals that I've seen, but It is apparent that if you land the 737 without removing all of the drift the mainwheels will twist slightly....and remain twisted until the next landing. Sounds feasible, but looks very odd!

Heavy-landing has hit the nail on the head. The 737 can land without the drift being removed (very uncomfortable and tricky feet work required during rollout, certainly possible but not recommended ) The resultant load placed on the landing gear is accommodated by the landing gears design, (torsional moment?) by twisting. The aircraft then tends to taxi like a homesick crab.

There are shimmy damper installed on each Main Gear and they make it what it looks like.
There mainpurpose is to allow crosswind landings with grabangle down to touchdown.
When the aircraft is taxing on a windy day, then it looks like sliding on the taxiway.

next time you are near a 737, look at the front of the main landing gear truck. don't know all the specific terms for the parts, but there is a horizontal shaft over which the lower gear truck can slide back and forth over. it is built in to allow a good bit of crosswind slack and taxing steer give.
next time you see one taxing in front of you and it seems crooked, take note of the wind and it will be seen to turn slightly into the wind, or if the taxi way has a bit of a slope. or if no wind, it might be related to the last direction of turn before the straight taxi which you are seening at the time. at the gate, the gear will be offset in relation to the last minute steering just before stopping.
it is built into it for sure.
sorry i do not have the latin terms.

A captain once told me that the 737's mains can twist up to 3 degrees to aid in x-wind landings, due to the fact that they are limited in their AoB on touchdown due to the engine pods, just like the 747's. Have taxied behind many 73's and they always point into wind.
