How to lower an 03 vibe gt

Post by revstohigh »

we will start with the front

1) First things first jack up the car and remove the wheels

2) remove the 14 mm bolt holding the brake hose and abs wire

3) remove the sway bar end link . hit it w/ som wd40 first , then use an airgun till it spins freely , now use a hex bit and a box end wrench to remove the nut (you will most likely need to hammer the hex bit in to get a good bite)

Image

4) remove the two 22 mm nuts and bolts that mount the strut to the steering knuckle (if you arnt changing springs you may want to mark the knuckle for alignment purposes)

Image

(Make sure you dont let the susspension hang to low ) otherwise you could damage the hose , wire , or axle do not let axle pull out of its sockets make sure it rotates smoothly before putting back together

Image

5) remove the 3 12mm nuts on the strut tops (be carefull not to let it drop) or you may damage the axle boot

Image

6)Mark the spring and strut with a line from top to bottom . this will ensure that your hat is inline with the lower mounting when reinstalling . and help with getting spring to sit correctly on the perch and rubber top
i usually use white out for this

Image

7)some will tell you you will need a spring compressor to take the spring strut assyembly apart . you don't just make sure you are pressing firmly down on the air gun and when it pops it will only pop up a little bit , (if reinstalling oem springs you will need spring compressor ) but lowering springs are shorter than oem springs so you can get the hat's back on by just pressing down a bit

8) take the assembly apart one piece at a time take care to re install all parts in the correct reverse order and don't get the washers flipped upside down

9) make sure before you tighten the top bol down that the square part of the shaft sits correctly in the hat (otherwise you will get alot of banging and part failure)

Image

10)re install the assembly to the vehicle

Image


11) if lowering i would tighten lower bolts with as much positive camber as you can because it is bound to be negative when all is said and done
some may require a camber bolt

ok now on to the rear (the fun part lol) the rear is a little tricky

1) raise vehicle and remove wheels (always use a jack stand)

2) remove all rear interior panels from rear doors back

Image


3) remove lower nut and wiggle (or pry if needed) to remove strut from lower smounting stud

Image


4) remove the 1 upper mount bolt from bottom , then the 2 upper mount bolts from inside the car

Image


5) remove strut assyembly from vehicle

6) same as front mark a line the length of the assembly with white out to ensure proper alignment of all parts

7) the rear springs are much more compressed so be very care full when removing nut from top . if you push down firmly on air gun it will pop up a bit just make sur not to lose the nut and washer if they do go flying

8) take apart and re assymble with new parts

9) you will need something to compress the new springs on the rear , i used long carpenters clamps (the kind used to hold things together when being glued) . they work very well when you place them on the top of the hat and bottom perch

10) re install rear strut

11) lower vehicle , drive for a week or so to let springs settle , and then get it aligned

10) happy tuning now go see how fast she corners !

update .... the new ebay $78 springs are way m ore than a 1.5 drop more like 2.2
my struts didnt pop back up on there own so i should have known they were no good but at that point it was either put it back together stock or get new on the spot ... so needless to say it bangs on every bump bigger than a manhole cover :-(
so i will be getting tokico's next month after rent is paid . i love the look and i like the cornering but man does she bang on bumps.

are you guys running bump stops ? if so did you cut them put em back in full size or delete them ?

How to lower a vibe by Jason McDonald. Pull the old crap out… Drop in some sweet Coilovers …. Don’t worry about an alignment because the camber is better for handling....J/K good little write up with pics for reference.

PS make sure you get that alignment or some new tires.

just a few notes for others:

1. for those of us in the rust belt, its best to spray all nuts/bolts with penetrating lube at least 24h before you plan to work on a 10year old car

2. i havent ever found ive needed to use a box wrench and hex socket with the sway bar endlinks, i just use an impact wrench. when/if its really stuck, use vice grips to grab the spindle on the back side of the endlink and tighten it down with a wrench so it doesnt move AT ALL. then hit the nut with an impact gun.

3. there are actually little nubs on the rubber at the top of the front struts that are supposed to face outward (aligined with the attachment location of the strut to the rest of the wheel hub)

4. you DO NOT need to remove all the plastics behind the drivers door. just remove the cargo covers and the trays (with the child seat brackets. and you can get to the 2 nuts at the top of the rear shocks
