Ion to Cobalt spring conversion
I got a how to here but #1 would hate for the dancing pickle to see it (TTR) and #2 its delta suspension so it should be over there... but anyway its a Redline thing so here we go .
Step1. The task is to install cobalt size Pedders springs on a Redline. The top hat and spring diameter are different on the Cobalt, (smaller) so stuff has to happen. You need some Cobalt parts ( new top spring plate) some secret shims from me, but I dont make them so you can get them yourself PM me for the size you need and what it is to buy, or I can send them to you for 10 bux. I buy all the GM parts from Tom at CED, he has the part numbers you need. I shoulda replaced the lower plastic gasket for looks I have it I did not. Damn fone keeps ringing while I work .....
Step 2. Jack the car up jack stands etc, or hoist whatever do it safely, remove wheel.
Step 3. support control arm, undo top spring retainer,
remove strut to knuckle cross bolts ( takes a hammer to knock them out as they are a spline fit in the knuckle dont damage the threads, put the nut back on if you are a clumsy ijiit or use a center punch) undo abs connector remove abs wire retainer plate and remove strut. Be carefull not to pull back on rotor as you will pop the axle out of the trans and spill fluid like I did. (Put a drain pan out next time , Qwik)
Step 4. Go to spring compressor and remove top mount.
This is a modified strut with Cobalt top plate but the spacer was not enough. So the top mount rubs on the spring hat; see the witness marks.
If there was no spacer there is brutal big spring clanking and banging. Ask me how I know? Coz GM told me at the roving grounds that it was a straight up swap hat for hat. They were wrong...
Step 5. Install new shims (new bearing is worth it they are 50 bux each silly plastic things made in Canada at a plant in Stratford Ontario. I cant get into the plant. Tried to get them direct to save money. No way. Just so you know and it is clear to you why, the bearing company is called FAG. 'nuff said.
Try to ignore the soft jawed vice grips to hold the strut up while I took pictures....no helper.....
Step 4 . Line up the top spring hat tab with the end of the top spring coil. VIP.
Torque stuff up. On the Redline the top strut mount is a simple stud so it dont take big torque if you reef on it you will pull the stud out.
The nut to shaft takes the big torque (81 ft lbs check Mavens sheet here) then the rubber isolator goes on. Use anti seize on the threads of the little torx bolts. DONT overtighten these little suckers. Do them up with a 1/4 drive ratchet....
Step 5 Put the sucker back in the car.
You are done. Notice how the steering does not bind any more, and pull one way or the other, if you did this job without spacers...
You are welcome.
