Hey just wondering about your roof racks.. I carry my canoe often and will be look for some cross bars like yours, what brand are those? Thanks.I know there are plenty of YouTube videoed on this, but here’s what to expect for the install of the ECGS diff carrier bushing on my 2024 SR5. If you aren’t familiar, all the 4wd Tacomas from second gen (something like that.. feel free to correct me) onward use an idler needle bearing to support the CV on the drivers side. When the truck isn’t in 4wd, the cv turns against this needle bearing and when the front is raised at all, to where the CVs are at any downward pitch, you will feel a vibration at street and highway speeds through the steering wheel due to the side loading on the not so tight tolerance between the shaft and bearing. Here’s the step by step of it.
Separate tie rod end.
Remove lower mounting bolts holding lower ball joint assembly to spindle.
Remove dust cap from hub.
Remove CV nut using 35mm socket, then separate CV from spindle
.
Prop or tie the spindle out of the way and be mindful of the brake lines/speed sensors wire.
Pry the cv out, be careful of the dust shields but these can be straightened if bent.
Despite the loud vibration, the shaft surface against the needle bearing is in great shape.
Insert paper towel or plastic bag into splines to prevent extracting tool from falling into diff.
Set slotted nut from extractor tool in behind needle bearing(I had to slightly bevel the edge to get it in easily.
After popping the oil seal out, thread in the all-thread and plate making sure the slotted nut is seated only against the needle bearing and pull it out. You will run out of length and need to put supportive backing between the plate and the diff to get it all the way out.
No damage found on my needle bearing thankfully despite the intensity of the vibration.
Using the driver, take your time lining up the bushing and pound it in. The driver will bottom out when it is flush.
The bushing should look like this when correctly seated.
Install new oil seal.
Line up splines and pound shaft back in until it’s all the way in!
Putting everything back together is just a reverse of the Teardown, but I like to add anti seize when appropriate. Be sure to either top off or replace the diff fluid before putting the wheel back on.
With the installation complete, the vibration has completely disappeared. I consider this supporting mod to be non negotiable with any height adjustments to the front of the truck no matter how slight.
