cmoney23 Posted April 20, 2012 Report Share Posted April 20, 2012 Well since i got lowered i think my front differential started to growl more than what it did before lowering it. It only growls when i turn at low speeds. yes i know this is a common issue with these trucks. I did just change the fluid with 2 qts. of valvoline 80w-90 GL5 dura blend gear lube about a month ago. Is this something thats just gonna go out on me soon, or something that could take awhile. When i changed my fluid i did have some metal shavings on the magnet. No chunks or anything like that. Am i in for a rebuild soon or drive it till it goes? Any suggestions? Quote Link to comment Share on other sites More sharing options...

RebelOne Posted April 20, 2012 Report Share Posted April 20, 2012 (edited) I will never see -24 degrees F, I dont think you will either. Thats the only thing that they talk about. I use it in my 03 SSS and no problems. I think it made it smoother. Anyways, to each their own Edited April 20, 2012 by RebelOne (see edit history) Quote Link to comment Share on other sites More sharing options...

f1ss Posted April 20, 2012 Report Share Posted April 20, 2012 I had every single liquid changed at 49k to all dealer synthetic fluid and no problems to 63k. Then again in that bulletin it states for trucks built after April 03, and mine was built in April so maybe its luck of the draw, or the time of the build.

JC03SS Posted April 21, 2012 Report Share Posted April 21, 2012 I've had that growl for 55k now I run 75 90 amsoil full syn Gear lube and every time I change it the magnet looks like don king. I guess they just do it. Quote Link to comment Share on other sites More sharing options...
