SOURCE: Can anyone give me some instructions to add a leaf

This should be pretty close for you since most add a spring(s) are pretty much the same.

Note: Check U-Bolt length prior to disassembly, Longer U-Bolts may be required.
1. Park the vehicle on flat level ground. Set the emergency brake and block the tires.
2. Raise the vehicle so that the tires slightly touch the ground. Support the frame rails using jack
stands.
3. Remove the U-Bolts from one side only. Remove the spring eye bolts and remove the leaf spring
from the vehicle.
4. Place 2 C-Clamps around the leaf spring as shown in Photo #1. Tighten C-Clamps against the
leaf spring.
5. With C-Clamps tightened onto leaf spring, remove the center tie bolt using a pair of vice grips to
hold the head of the bolt. “Slowly” remove the C-Clamps to release the spring tension.
6. Note the location of the tie bolt hole in the add-a-leaf. If the hole is not centered, measure the factory
spring to determine the long end and short end. Be sure to install the add-a-leaf with the
long end towards the long end of the leaf spring. Install the new add-a-leaf onto the “bottom” of
new leaf spring. If installing more than one leaf per side, install the longest first, then the shortest.
7. Use a screw driver to line up the tie bolt hole in the leaves. It is recommended to leave the screwdriver
in to help keep the leaves aligned as you tighten the C-Clamps. Tighten until there is
enough space to install the new tie bolt. With tie bolt installed, tighten the nut by hand. Then continue
to tighten the C-Clamps. Repeat this process until leaves are pulled together. See diagram
below. DO NOT USE THE TIE BOLT TO PULL THE LEAVES TOGETHER. THIS CAN RESULT
IN AN EXPLOSIVE DISASSEMBLY AND POSSIBLE INJURY!
8. Tighten the center tie bolt to torque specifications provided.
9. Reinstall leaf spring into the vehicle. Install U-bolts. Repeat this process on the opposite side.
Torque Specifications:
3/8” Tie Bolt = 17 Ft. Lbs.
7/16” Tie Bolt = 27 Ft. Lbs.
1/2” Tie Bolt = 41 Ft. Lbs.

SOURCE: suddenly loose steering

I had this problem and it was the rack bushings. I replaced them with Energy suspension ones. Toyota does not sell bushing for it, they sell the complete rack. You can check it by getting someone the turn the sterring wheel when its running. bend down next to the truck and watch the rack if this is the problem you will see the rack moving on the bushings.

SOURCE: Check engine light on tacoma prerunner double cab 2003.

Take it to a place like Autozone, where they will read the stored causes for you for free. If it is intermittant, such as going up a hill or on wet mornings, then don't worry about it. If it is all the time, after say 40,000 miles, it could just be a timed maintenance indicator.

Batt light stays on, what's the prob. How do i check?


  • your battery light is on because your alternator is going out to to double check start the car and pull the negative battery cable off if the car dies then you need a new alternator that’s a really good way to check if the care douse no die then take your alternator to an AutoZone and have the Ambridge checked but that’s the only reason your batt light will come on is a bad alternator

Engine Light On


At first it will cost you from $60-70 (Midas) to nothing if you go to the nearest parts store (you need to call them and ask if they do it for free, I can suggest Autozone) and do the computer diagnostic of your car to get the malfunction codes. After you get the codes you can call the repair shops and get the estimate. But first you can try to do to change the gas station and use a fuel injector cleaner (form $1 to $6 in Walmart).
Good Luck
