2015 suburban ltz

xRogrimx · October 19, 2017

My wife drives a 2015 Chevy suburban Ltz. She thinks it road smooth back at 38k miles, now that it has 58k it rides so rough. We just put Goodyear ls2 tires on it, and I can't even explain when you ride in the far back it just jarrs your body. On bumps you can get airborne. I think it has always road rough. Any help would be awesome. 2015 Chevy suburban ltz 4x4, 5.3l engine.

If your LTZ has self leveler air shocks in the rear, you may have a ruptured bag or bad compressor. Good luck.

Bags look good and yes it has the auto leveling there is a greasy build up on bags and shocks on both sides when I bounce on left side bumper it bounces way more than passenger side

My wife says she never hears the humming sound anymore like the compressors aren't running I checked a fuse under the hood...5 and 45 and 33 in the cab and they all looked good.

I just pulled air lines off both bags. Both had just a short blast of air. I marked fully depressed ok shock, went and started the vehicle compressor ran for about 8 seconds and bags raised 1/2 an inch. Is this normal 8 seconds of air and a half inch of raise.

I had airlift airbags in the silverado, 8 seconds of air would level me off with a full load. Did air bags in my wifes suburban lt and with a full load approx 1000 lbs leveled off in less than 15 seconds. It is aftermarket tho.
