Q: What are some of the signs that my u-bolts need to be replaced?
A: Rusted and bent out of shape are the two most visible reasons to replace existing u-bolts. Other factors such as being stretched, broken or pitted are clear signs that the bolts need to be replaced as well.
Q: What exactly are u-bolts used for?
