Interesting. I was kicking myself the other day for not having them take pictures of my intake valves when they did my AFM lifter replacement a couple months ago. I'm pretty sure it's the cause of my (very slowly) increasingly rough idle.
Got done installing all 4 today and took it on a short test drive. The driver side front shock was shot and passenger was close behind. After the work, the rattle is gone and it rides as well as I ever remember. The harshness I'd accumulated from the level kit, e-rated ko2s, and worn shocks is gone. We did put the extra spacer underneath and I'm happy so far. I'll report back if anything changes. Thanks all. I should have gotten these from the start. Sent from my SM-G892A using Tapatalk
It's the stock 18" wheels. I'm not sure about the back spacing. As for the tires they're not much bigger and it'd probably be fine, I just wouldn't want to find out the hard way. Sent from my SM-G892A using Tapatalk
I already have larger tires and am not willing to do the work twice if I get rubbing. The front end is lifted 2.25 inches now with about 1" of rake from my rear add on springs. It rides fine. The truck looked like a bloodhound tracking a scent when it was stock and I don't want that look again. My issue is with a bad shock.
I got under the truck with my neighbor who is a mechanic and we don't think it's the ball joints. There is some motion in them but it's even on both sides and the noise only comes from the left. Also, when we lever the tire to check you can hear and feel a tap/clunk in the shock shaft. I'm pretty satisfied that either the shock is damaged or the upper strut mount is. I can't get a hold of any of the upper mounts in under a week so this is on hold for now. Sent from my SM-G892A using Tapatalk
Well, I live on a dirt road, so yeah bumps are very common for me. I thought I remembered reading that 2.25 was safe for the ball joints but I guess not. I wasn't aware of upgraded ball joints other than the UCAs that rough country offers. I don't think I need to go to a uniball. That seems a bit extreme, but what do I know.
Well, my 5100s have arrived and I was planning to tackle the install this weekend with a buddy. He used to be an Infiniti tech so he's got access to a wall-mounted compressor. My plan is to remove the existing 2.25" level kit, set the 5100s on the highest setting and re-use the 3/8" spacer under the 5100 to get back to 2.2" of level. I'm doing this because my truck's had a suspension-related rattle for some time now and has recently started rattling and creaking very badly when the suspension flexes. When we rock the truck side to side, we feel the vibrations from the creak in the shock/spring assembly much more than anywhere else. So, I am about 60% sure that the problem is in that assembly. We can also see the top of the shock move in the mount ever so slightly (a few mm, nothing more) when viewed from above. It's almost like a bushing is failing but I don't know if it's normal or not. I can't get a clear view of the other side.. The motion I'm talking about is in the center section of part 8 in the diagram. We'll check the ball joints as well just in case, but I thought 2.25" was supposed to be safe on those. Should I hold off on the replacement until I can get new top mounts in? I'd hate to tear it all apart to have to wait a week for parts. I daily the truck, but I do have alternate vehicles I can use. If it is the ball joints, should I replace the UCAs with the RC ones or just change out the ball joints with OEM or MOOG units?
Yeah, it's funny, but I live in NE FL and it has no bearing on people's ability to drive in the rain. If a rain drop falls, my commute doubles to an hour -not because people slow down... Just because they didn't and are now stopped in the travel lanes on the interstate waiting for FHP to come take a report. Not that I'm bitter or anything. Sent from my SM-G892A using Tapatalk
My dealer would have laughed at me if I asked for Bilsteins as a warranty replacement. Hell they wouldn't even install a non-factory tire on my dime. You've got a good one there. Sent from my SM-G892A using Tapatalk
Not running a range, exhaust, nor tune. Motor is stock. I have an aem dry filter and the airaid MIT. Not sure why it happened, but the service writer instantly recognized it. I think he said he thinks it's number 6. Not sure if it's one of the AFM ones or not. Sent from my SM-G892A using Tapatalk
Well, I was merging onto the highway this afternoon after work and felt a weird klunk-rattle. It was a new one on me. It seemed to drive okay, had good oil pressure, and didn't set the CEL so at first I thought I'd hit something in the road. But within a couple miles I could tell something was up. Accelerating up hills from a coast it would stutter and sounded like a mallet was hitting the firewall. I couldn't really hear anything specific in the cab. I was only a few miles from the dealer, so I called them and luckily enough got my normal service advisor. He's a decent guy. Never tried to screw me. I said I was coming in. When I got off the interstate the truck didn't want to accelerate all and was making that pounding noise. When I pulled into the dealership and hopped out, I could hear the lifter clacking. He instantly recognized it. I'd never heard one in person before, but it sounds like the right diagnosis to me. He said it should be covered by the 100k powertrain warranty. I don't see why it wouldn't be, but I've never had warranty claim with Chevy before. So, we'll see I guess. The bad news is that he said worst case is 1 month to get the truck back. I choked. I let him know I have a camping trip in about 3 weeks, but that didn't seem to sway anything. He said he'll know more on Monday. So, that's how I spent my evening.
