Just installed my Bilstein 4600, tips and my Commander Leveled out?
I just replaced all 4 shocks on my Commander yesterday, Bilstein 4600 and Moog Strut Mounts.
Perhaps the springs still have to settle in, but my Commander doesn't have the forward rake of the stock struts, the front is raised a little bit for a much more level appearance. I've only driven about 30 miles, perhaps the springs will settle into the seats and mounts, but I like it and hope the blistein 4600 have a bit higher spring perch to do this on purpose.
A couple things, keep in mind I live on the edge of the rust belt, so I did have undercarriage corrosion to deal with, as few dead in the middle of the rust belt will have worse trouble.
The lower Clevis Bolt, the one that often rusts/seizes and can't be removed.
*I soaked it in PB Blaster everyday for a week before doing the job. The nut came off easy, but the PB Blaster did NOT make inside to the collar in the bushing.
*Use a 21mm wrench to turn the bolt head. The combination of twisting and pounding the clevis bolt with a sledge was what got it out for me, just pounding it would do it, the blows of the sledge did help to break up the corrosion a bit, but the twisting with a wrench helped break the rest free.
Disconnect the sway bar end link. The way to get the strut/shock assembly out after all is disconnected is to push the upper and lower control arms apart to open enough space for it to come out. The bushings will resist you on both arms. Push up on the upper control arm with one hand and pushing down on the strut/shock will push the lower arm down to get it out. The sway bar will connect both lower control arms, so when you press down the lower control arm on one side, you actually pressdown both lower control arms linked by the sway bar. Disconnecting the sway bar end link will let the lower control arm drop down much farther to get the strut/shock out.
Rear shocks, I didn't soak those bolts in PB Blaster, like a dummy, I didn't even use some while removing the lower bolt on the Passenger side and encountered some real resistance from corrosion. I just used a bigger breaker bar and I snapped the bolt off in the welded on nut in the axle. I tried drilling it out, the but the remaining bolt was too hard. I ended up cutting the nut off the axle with an angle grinder and cutting blade, getting a new bolt and nut from the hardware store, grade 10.8.
What a different the new shocks make. The old ones had some dead bands in them, small, but the passenger side front strut/shock was near blown out, big dead band. I didn't think the ride was that bad before, I had to pay close attention to tell the bumps in the road where worse than I remembered when new. With the new Blistein's its so much smoother and controlled.
