最近，挂1，2档时，有"突突"声，3，4，5，6挡没有。
判断是离合器磨擦片快磨光了，需换clutch kit (clutch disc, pressure plate, slave cylinder).
换离合器是大活，我在德州，墨西哥店工时费，$700。但我想自己先试试。前阵子，harbor freight 买了cherry picker ($250). 还缺两样，(32mm, 21mm sockets), 扭矩250 ft-lb 的扳手。都从walmart 订
一套sockets 8-32mm, $36.
50-250 ft-lb 扭矩板手，$39。
这周末，socket 到，我看看32mm 是否符合。下面是过程。
25inch break bar, loose lug nut.
Prepare jack at the front, on subframe.
Set parking brake, chocks the two rear wheels.
Set on jack stand.
Take out the front right wheel.
Check the 32 mm socket fits.
Also checked the brake pad thickness, it is around 5mm, after 13 years, 85k miles.
Set the torque wrench to 100 ft-lb.
Lower the car and torque the five wheel lug in a star pattern.
