NOTICE
Replace used wheel bolt
If a wheel bolt is removed for tire service, replace it with a new, unused bolt
from Permobil and tighten it to the recommended torque. Also, inspect the
drive axle and wheel rim for any damage. Damage to either part can cause
the wheel bolt to loosen or fracture. Because the TUF-LOK thread lock fluid
wears off, Permobil recommends that wheel bolts only be used once.
