How to Properly Check
Your U Bolts
Many vehicle-towing owners and heavy machine operators
concern themselves with maintaining proper suspension—as they should!
Supplementing your truck, van, SUV, or recreational vehicle
with the proper suspension system will make all the difference in prolonging
the life of your vehicle. You can have a great-looking vehicle with a monster
engine, but if you don’t have the right kind of suspension system installed,
your vehicle could flatten out making every bump in the road an uncomfortable
one. It could also cause a greater liability for any fragile goods that might
Without the proper suspension system, the chassis of your
vehicle will wear out quickly rendering it inoperable. That is why
are such a crucial part of a vehicle’s suspension system. What is
equally as important, yet often overlooked, are the U-Bolts.
What are U-Bolts?
A U-Bolt is the part that connects the leaf springs to your
chassis. It is considered the bolt that secures everything together. Leaf
springs are thick, so it takes more than a regular type of bolt to install it. The
U-Bolt basically serves as an industrial type of clamp that is sturdy enough to
endure oversized loads as well as tough terrain, but also is easily removed
How Do You Know When
to Replace U-Bolts?
Just as leaf springs need replaced, so do U-Bolts. Leaf
springs endure an immense amount of pressure. They are only able to do this by
staying in place, and U-Bolts contribute to this. However, there is only so
much pressure a U-Bolt can take after a certain amount of strain.
As weight is placed on the leaf spring, the U-Bolt also
absorbs the energy from that weight. When the leaf springs flatten out and then
springs back into its original form, the U-Bolt keeps it in place preventing
them from ‘springing’ out of place. This amount of pressure can wear on U-Bolts
and may sometimes need replaced before the leaf springs.
Depending on what kind of task your vehicle has, you might
need to check to see if your U-Bolts are in good condition. Here’s what you
need to do:
Check your U-Bolts every 24,000 miles or 6
Make sure that they are secured tightly. If they
are loose, tighten them immediately.
Check the bend of the U-Bolt to see if it’s
cracked. If any part of the U-Bolt is cracked, replace it immediately.
Verify that the minimum inside radius is
satisfactory. For example, the minimum requirement for a 1” U-Bolt should be no
less than ¾”.
