    03 Suburban LT Steering Issues, Wandering and Wobbly and Loose

    The only code it immediately throws again is the C0300 rear propshaft speed sensor malfunction. I watched live data this morning and neither front or rear propshaft is reading any rpm speed. It's just strange that it's never thrown the service 4wd unless I was in auto 4wd, but now it throws it...

    Alright Fless. Scanned it and it did FINALLY throw codes. C0300-Rear propshaft speed sensor malfunction C0305-Front propshaft speed sensor malfunction C0374-General System Malfunction

    Yeah it doesn't clunk going into auto. It's been awhile since I've had to mess with these trucks and 4wd so I'm a bit rusty on it. However the other day we started driving it, indicator light showing 2wd and the service 4wd light came on. I haven't scanned it yet because I've been super busy...

    I don't think so because when you switch into 4lo and back out of 4lo you hear the clunk and switch. I don't know if it's supposed to clunk going into auto 4wd. From what I read it locks the front axle but doesn't engage until it detects slip. Putting it from 2hi to 4hi there's no noise. I...

    Oh yeah I did that too. It didn't change anything unfortunately. It's just one of those things that's driving me insane. Because I've had 5 of these trucks and this is the only one that's been like this. I've had an 01 Yukon XL, two 04 Suburban's, 04 Sierra and now this 03 Suburban. Every other...

    03 Suburban LT Steering Issues, Wandering and Wobbly and Loose

    And I've done that. My scanner can do pretty much everything. It's not a cheap one. There are zero codes. Trust me. It'll throw service 4wd but the truck will drive just fine. Live data shows everything switching like it should, goes in and out of the different modes just fine. I pulled the...

    03 Suburban LT Steering Issues, Wandering and Wobbly and Loose

    Yeah that's what I thought. But there were zero codes. Only one I've had was an evap code that comes on because my filler neck has a hole in it and leaks fuel if you fill it fast. My scanner isn't one of the crazy expensive ones, but was still a $600 scanner and I can read and see all codes...

    I just looked at everything on my scanner. Live data, actuation tests. There were no codes. Watching live data while switching through all the modes and everything looks great. Goes into each mode just fine. And out just fine.

    Could it be bad wheels? I would have thought Firestone would have said something if the wheels were warped or out of round. But it wouldn't surprise me if they didn't even pay attention. It rides smooth as silk though which is where it gets me. Besides the wobble which feels like it's in the...

    Haven't seen anything like that. And I have checked.

    There's no fault with the abs system. When I got it it did have the typical low speed abs activation where at 10mph you feel it in the brake pedal. But that went away when I did the hubs. It doesn't feel like it's in 4wd when you're driving. Switch shows 2 Hi. If I push the auto 4wd button and...

    03 Suburban LT Steering Issues, Wandering and Wobbly and Loose

    My biggest complaint is this... The front feels like it's wobbling all over when backing up and when going forward at lower speeds. The wobble is what I have the biggest problem with. The steering wheel has no vibration, smooth as silk. But why the thing wobbles and feels like the tires are...

    I've had it for a few months. It's always had an issue, but the tires that were on it when I bought it were trashed. It's never been wrecked.

    It's on correct. I fortunately have done work for 16 years and I make sure everything is installed correctly before I finish a job.

    03 Suburban LT Steering Issues, Wandering and Wobbly and Loose

    Yeah, I'm not putting much more into it, body is rusty(as we live in Ohio and it's been through 21 winters in Ohio) and while I only have $2300 including what I paid for it, it's not worth dropping much more into. My last suburban i had was an 04 Z71 and the steering box was beyond shot, and...
