Tackled this job this past weekend. It was pretty easy and it cured my squeaky clutch pedal
Parts used
Spring part number 90507-14030
Pedal shaft bushings (requires 2) 90386-13007
Parts cost less than $10 from my local Toyota dealer
I didn't photo-document the entire process but here's the basic approach
1. Remove evap cannister/box from engine bay after disconnecting all hoses and 2 electrical connectors
-this gives much better access to clutch MC
Break but don't remove the 2 MC bolts (12mm socket)
2. Disconnect retainer spring pin from pedal shaft
-this is through the pin the new spring will connect to the pedal shaft
Remove the plunger pin,.don't lose the spring washer on the pin
3. Remove upper pedal bracket bolt from under dash
(12mm socket)
4. Disconnect upper and lower clutch switch electrical connectors
-the upper one is a bugaboo
5. Remove clutch MC bolts and pull the MC back, clearing the studs
6. Remove the clutch pedal bracket
-twist down and to the right while pulling back
-be careful of the wiring behind the dash
Once the bracket assembly is out you'll need a 14mm socket and wrench to break the pedal pivot bolt.
The spring comes out pretty easily, you can use a channel lock to squeeze it and remove the ends from the bracket.
The bushing were actually still there but cracking
The spring had cut itself a channel which is where the squeekiness was happening
I cut the tab off as recommended by a few others to remove risk of interfering with the new, linear spring
The bushings on my pedal shaft were actually still good, but I replaced them anyway since I already bought them
I greased the pedal bushing shaft exterior and installed it back in the pedal shaft with the 2 new end bushings, then installed the pedal shaft back in the bracket, torqued to 25# ft, the point where the lock washer flattened out.
The reinstall back into the truck is basically the reverse of removal.
The spring clips onto an obvious loop under the dash and then attaches to the pedal plunger pin, just like the brake return spring on the brake pedal shaft.
A quick function test and I was in business, squeak-free.
