On my Model 3, I had toe in on the left and neutral on the right. On landing the aircraft wanted to divert to the right so hard the I could hardly keep it straight... it was a struggle.
To measure I used a straight edge (6 foot level) on the rim of the wheel. To get an accurate line, I used 3/4" nuts as stand-offs from the rims to the straight edge.
By whatever means, make both neutral.
The method of correcting by putting a pipe on the axel and tweaking to straighten in not intended to bend the axel, it is intended to twist the landing gear.
