What can fail
The bolts securing the power steering assist cylinder mounting bracket can loosen. If the cylinder detaches, steering may become restricted and the front brake hose could be severed, causing loss of front braking.
What the fix does
The bracket bolts will be replaced with new hardened bolts, washers, and locking nuts, then torqued to proper specifications.
