FAQs— Toyota Leaf Spring
- What are some preventative maintenance procedures that I can do to make the operations of my Toyota leaf spring smooth and to keep my ride comfortable?
- I noticed a problem in my ride and during troubleshooting, I found that one of the leaves of the leaf springs is corroded. Can I replace just the problematic leaf, or should I replace everything?
- Can you share some tips on how to properly clean my Toyota leaf spring?
- I am bothered by the leaf spring rattle caused by looseness of the rivets that hold the metal guides to both ends of the springs. How can I deal with it?
- What are some of common causes of Toyota leaf spring failure that I need to watch out for?
- How often should I check and retighten the u-bolts of my Toyota leaf spring? And what are the risks if I fail to do this?
- Most people today use coil springs, but I have a friend who is converting from coil spring to leaf spring suspension. What's the benefit of doing such?
As you go through humps, potholes, and any other kind of road bumps, your vehicle’s weight shifts and will be handled by the leaf springs. The stress suffered by the springs causes the suspension to sag. When this happens, the leaf springs can be maintained by pre-setting them to bring them back to tiptop shape. The u-bolt at the center of the leaf springs should also be retightened to prevent the suspension from sagging further. It is also important to make sure all the leaves are in good condition. If one of them is rusty, bent, or damaged in any way, consider replacing it. The entire leaf springs should also be lubricated regularly to make all its components work smoothly.
No, you don’t have to replace everything. In some cases, you can replace the individual leaves, such as when a strip is out of place or when one of the leaves is rusty, old, or corroded. However, automotive concerns like this may need the expertise of a pro or an experienced DIYer, at least.
Check your vehicle’s manual to find out the cleaning interval recommended for your leaf springs. If you own a modern Toyota model, the leaf springs are more likely to be situated on the rear suspension. You may need to raise the vehicle’s rear to access and clean the springs. If you notice the leaf springs are coated with grease and dirt, you will need to spray proprietary degreasing fluid and then brush the dirt off using an old scrubbing brush. If the dirt isn’t that thick, you can simply use a wire brush to remove them. Make sure to work your brush vigorously in all the parts of the spring, as well as around the clips that are used to secure the leaves together. After cleaning, wipe the springs and the clips with a rag. If your leaf springs are the type that necessitates lubrication, then apply silicone lubricant.
If that’s the case, you may consider installing leaf spring insulators. Make sure, though, that the insulators are designed to fit the suspension of your truck. It could also be that the area around the guides needs some cleaning. Have them cleaned and use some RTV silicone around both sides to secure the guides in place. If you still have no luck, you can also try knocking off the head of the rivet and then have it replaced with a heavy-gauge bolt, nut, and lock washer.
Among the issues that may cause your leaf springs to fail are u-bolts that are not tight enough, particularly on trucks and other vehicles that carry heavy loads. And then there’s corrosion and fatigue, which are usually dependent on the weight of the load you frequently haul, on the place where you reside, and on how well you maintain your ride. Overloading the vehicle’s leaf springs also give them undue stress, leading to failure.
You have to retighten the u-bolt nuts of your new or repaired leaf springs after your first 500 miles, then after the first 1,000 miles. After that, you have to follow the recommended retightening intervals as stated in your car manual. Failure to retighten the u-bolts can result in serious suspension damage.
The set up and function of a leaf spring suspension is simpler than coil spring. Leaf springs are also sturdier, and hence are more capable of carrying heavy loads without much deflection compared to coils. It’s also much easier for a DIYer or a mechanic to raise or lower a truck that’s fitted with leaf springs.
