How to Adjust Coilovers

I have a brand new 2019 TRD Sport lifted with 2.5 Fox Coilovers with resi's up front.....I have rubbing but I think it is because I need to adjust my shocks up some......anyone have any experience on how to do this or best way to do it. I seen on youtube a company recommend a 5/16 punch instead of a spanner wrench...

I measured real quick this morning and the back end seems to be higher by about 2 inches maybe...but again i measured not real accurately and very quickly...

Thanks for the help!!!!!!!!!!!!

 

Jack truck up, support at frame to take weight off of suspension. use spanner wrench. Turn to desired height.

 

It’s still gonna rub after lifting it when the suspension cycles. And yeah have the suspension dropped out then try adjusting. Also check to see if theirs a set screw!

 

Measure from center of your wheel to fender flares to get an accurate starting point. I cut a paint stick just long enough to fit inside the wheel rim and then marked the center of the stick. Then I could measure from my mark to fender flare to get measurement. My shocks came with a rod to adjust with.

 

I was going to go buy a 5/16 i think it is punch or rod from Lowes. Also....and I am new at this... why do I have to jack up the truck? Where do you suggest i put the jack to lift the truck up?

 

Jacking the truck up, takes the weight of truck off suspension/coilover. Jack at frame, let suspension droop.

 

OK and just count the turns and do it to both sides? I have a low profile jack that probably wont work may need to get a hi lift jack or something

 

Another thing... Don't use that 5/16 punch as a punch... Use it as a lever.

 

Low profile may work, under cross member jack point. I use my low-pro floor jack there.

Yes count turns same both side, unless you have Taco lean on drivers side. Tape measure is your friend.

 

Steps:

1. Spritz the upper threads of your coilovers with lubricant (I use WD-40)
2. Measure from the center of your wheel hub to the bottom lip of your fender. Determine the desired increase in height.
3. Jack up your truck and support with jackstands at the frame.
4. (Optional) Remove your front wheels. This gives you more access, but is not required.
5. Loosen the set screw, typically and Allen/cap head bolt on the thread body of the coilovers shock tube, just about the coil spring.
6. Use your 5/16" pinch and a pipe for leverage (if needed) to turn the collar (clockwise=more lift, reverse=less lift). Remember, 1/2" height increase on the coilovers yields 1" height increase overall.
7. Once you've achieved your desired adjustments, tighten up those set screws on the collar (snug)
8. (Optional) Remount your wheels.
9. Lower your truck down, remove jackstands first.
10. Drive your truck around the block, determine any rubbing, and let the springs settle at their new preload.
11. Confirm height adjustments via measuring in the same manner as before. Repeat if necessary or more height is needed.

As a point of recommendation only, keep your height adjustments within ~2.75 to 3" overall to prevent binding and CV joint wear.

Hope this helps and you have a warm garage to do it in!

 

Good call...thats what I meant. Thanks for the info/help.....I like this forum!

 

Going to be 65 sunday so thank god there. Good to note the CV angles. I had a diff drop put on as well. I think when they installed the coilovers they did not adjust to 2-3 inches because it really shouldn't rub. I had uca's and everything put on because I wanted it done right but I guess if you want it done right you still have to do it yourself LOL

 

There's always some fine tuning with this sort of thing. I see it as a good thing and especially for guys who want to get to know their truck.

Also, do some searching here on the potential consequences of a diff drop. The risk vs. reward factor is very high and they can act as damage multipliers in some severe cases.
