A How To replace your FRONT STRUT COIL SPRINGS.

Image


Difficulty level 1 (easy) – 5 (hard)
1 (easy) = some instructions on TRD is not necessary but please use your own judgment.
Use proper tools for the application and proper safety precautions.
Read all instruction provided or look it up on-line.

Image


Loosen lug nuts on front wheels and jack up the front of vehicle. Secure with stands and remove front wheels.
Image


Open the front hood to remove nut covers on windshield wipers with screwdriver as indicated.
Image


(Optional) you can take a marker to place a line as reference for installation or use tape to mark your wipers.
Using 14mm socket remove nut from wiper. Take care when removing wipers from gear bolt. Gently rock it back and forth until loosen, and then pull up slowly. You might want to use a protective cover on hood to avoid scratches.
Image


Remove 2 plastic fasteners on each end under the hood on the windshield cowl. press the center down carefully with a srewdriver. you will hear a clcik which will release it easy
Image


Starting on the corner of the plastic cowl gently pull up until the clips release as you work toward the center. The cowl will be in 2 half just work on each ends. Yellow arrow indicates other half on picture.
Image

Image


After cowl removal it should look like this. You can remove the rest of the windshield parts and cover if desired but not really necessary.
Image


Remove the nut on the sway bar linkage using 14mm wrench with optional 6mm hex key if needed.
Image


Remove bolt using 14 mm socket on the brake line/wire.
Image


Remove bold on the sensor wire using 10 mm socket.
Image


Remove plastic wire clip on strut carefully or use a flathead screwdriver on opposite end utilizing the hole to access the clip to release as the picture indicates.
Image

Image


When the wire is completely loosen from strut, place on side to keep it from damage.
Image


Remove the 2 nuts on the base of the strut. Use a pipe for leverage if need
ed. Take caution not to damage your fender wells since it will require extra effort to break it loose.
Image


When all nuts, bolts and wire are removed proceed on top of tower. Remove 3 nuts on the strut tower on each side. You can choose to loosen the nut on the strut or perform it later. This is also the best time to add the front strut brace when you reassemble the strut later. Remove strut carefully under the vehicle.
Image

Image


Remove dust cover on strut. Keep it in clean area.
Image


Clamp coil spring with proper tool. Tools may vary, please read the proper use.
Image


Place a screwdriver on a hole to keep strut in place as you loosen the nut. Keep all moving parts clean area as you disassemble the strut.
Image

Image


Reassemble parts properly as indicated by instruction. Since most lowered coil spring is shorter, clamping slightly or sometimes not necessary. Please do so accordingly.
Image


Reinstall strut in reverse order by installing the 3 nut on top of the tower. As stated this is the best time to install the Front Strut Brace. Install all nut and bolts as indicated using proper torque. Make sure to install wire sensor without twisting to reduce the likely hood of damage. Make sure to check the center nut on top of the strut after you install the wheels and place the car off the jack on its own weight. You can proceed to install the windshield cowl and windshield wiper as your last step.
Good luck and be safe.

Great write up. One trick that I do is that I break loose the strut bolt with the weight still on the car. ;) I have always found it easier to do it that way before taking off the tires. :D

He's referring to the bolt on the top of the strut under the dust cover that holds the spring on the strut. If you break it loose before you jack up the car it's WAYYYY easier to loosen that bolt later. If you wait until you take the strut out of the car it's a pain because the strut shaft will rotate as your turn the bolt so you have to use a screwdriver or something long to brace the top bracket.

I found out the hard way.

i know this is an old thread but i'll attempt installing these springs this saturday...i just want to know how far the center nut has to be tightened...i bought trd spring which had a full coil cut on the front....will the spring be loose even if the top center bolt is tightened because it looks so short??.....excuse me for the dumb question i have never dealt with any suspension work even though i have decent knowledge about everything else...

You will be able to start the nut without any problem even with the normal TRD spring. Make sure to torque to the correct figure once the weight of the car is on the coil spring. :thumbsup:

Thanks for the write up! this is actually way easier than doing this on my honda civic.. recently got my wife an 09 corolla LE.. and since i cant stand to leave any car stock... we got wheels and then decided it needed to be lower.. a friend sold me his old Tein's for his 08 corolla S.. worked just fine for me.

sorry jack, this is bad advice. its not so simple the way the OP posted it. one has to mark the wipers where they lay on the windshield because one tooth off on the reinstall and the wipers wont work right. the good advice is to not mess around with the wipers and cowl stuff. and why would people be doing this more than once? and even if it is more than once, no need to mes with the wipers. you cant even get your tools out of the garage in 5min.
This isn't true at all. I've taken my cowl and wiper arms off at least 3 times (various attempts at installing springs) and never once marked the alignment - my wipers work fine. It most definitely takes 5 minutes or less to do, even the first time. Be patient and deliberate. Wiggling the wiper arms off is the hardest part.

I highly recommend taking off the cowl and wipers so you can drop the struts to work at the springs.

Make sure to break the nut at the top of the strut BEFORE you put the car on stands.

I have checked Monroe, Advance, Nappa Auto stores and others for front Quick Struts (struts and springs as a unit) for my 09 Corolla 1.8 and it seems that they are not availble. Does anyone know where I could find them? Thanks, jdp
I've not seen them for the 10th ten yet. The only option that would be a LOT better performance would be coilovers. I wouldn't waste your money on Monroe or other low quality items. If your struts are bad you can always replace them with OEM KYB struts & install better lowering springs from TRD or Eibach. :thumbsup:
