Corrosion On Chassis Nuts And Bolts

[pm26]

Do you see many of the chassis nuts and bots corroded on your truck (spring shackle nuts, lower ball joint nuts, front tow hook bots, etc)? Some of these are aluminized, but still corrode.

if you want zero corrosion leave your truck parked in a climate controlled garage and never drive it.

I am just trying to find out if this is common on these trucks in normal use.

Yes it's normal.

[RyanbabZ71]

just think you do have road debris flying up under the truck when you are driving

It's pretty much the norm. I have the same year truck as you, baby the thing, get it undercoated every year and where the undercoat has come off its rusted.

 

If your home in Florida is near the coast you get an extra wif of salt in the air that is helping speed along the process.

 

I doubt that a climate controlled garage would help these trucks as they are starting to corrode before they are out off the assembly line.

Nothing corrodes faster than the rear exhaust manafold bolts on a 6.0. Mine rusted right off in 4 years.

Yes, coastal Florida climate is brutal. Everything will corrode eventually around here, even chromed plastics. I do not have any rust on the truck, just some corrosion on chassis bolts and nuts.

 

Do you have any rust on underbody sheet metal? I have not undercoated my truck except for the rear wheel wells and all of the underbody sheet metal and brake lines ar ein pristine condition. It's just some bolts that look like they have been submerged in salt water for a month. I guess I can replace some of the worst ones, although surface rust should not degrade them. What I found amazing is that my front differential fill and drain plug rusted so bad. Must have been uncoated carbon steel.

Rusting an corrosion is "normal", but if you have a newer truck (IE 2008+) then you're going to have a lot more rust.

 

My 2000 Z71 had what I'd call normal rust on the undercarage after 8 years and 155k KM. My 2008's rear axle/shocks/etc is BRUTAL, and it has 25k km. I ended up slopping on tremclad black to try to slow the rusting in case I ever need to swap shocks.

 

The newer ones(2010+) don't even have rust proofing enderneath. More cost cutting measures....

I wish I had coated all chassis bolts and nuts when my truck was new. I use CRC corrosion inhibitor spray which is much like rustproofing material. I sprayed this stuff along all door bottom inner edges and edges of hood where the sheet metal is creased. This kept water out and all the sheet metal is pristine. If I had done this on chassis bolts, they would look perfect too.

 

A can of CRC corrosion inhibitor will do the critical areas on the whole truck and costs about $ 8. Well worth the expense.

 

I know that corrosion of chassis bolts is pretty much normal, but my truck has been mostly sitting in the garage and I find the rate of corrosion a little too quick.

I hear you. I want my truck to last, as I do not drive it every day. I can certainly afford to buy a new one and pay the difference in cash, but is it going to be better than what I have?

I've sprayed my 08 with Fluid Film for the last few years to keep the underside looking good

Absolutely!..............LOL Probably not. Seems the "newer" these trucks get (every manufacturer), the cheaper they are made.
