Ls 6.0 starter failing?

[corneredge]

Intermittenly my 2008 6.0 is starting with a pause during cranking. The battery is good. Is this the starter failing? See video below.

The bigger the motor the harder it is on the starters.  I had a  big block in a 76 Malibu a very long long long time ago. It blew every starter until I put one I took off of a diesel garbage truck and used two batteries to crank it.  No trick performance parts back the 80's.. The game then was big engines in light cars ha ha.

Before condemning the starter, try swapping another relay in the crank relay's place in the underhood fuse block. It won't cost you anything to try, but if that's all it is, it'll save you $$$ on a new starter.

 

I didn't have time to watch the vid, so I didn't hear how bad (or not bad) it is - just going on what  you typed.

If you watch the vid it really sounds starter related. I will check the relay too

Thoroughly check all wiring/connections. Battery cables and any wiring connected to starter

[silveradosid]

agree with txab it sounds like connection problem

[corneredge]

Connections were all fine. Changed the starter this morning all good now. Thanks for the advice!

OP didn't say how many miles were on his truck, I assume a lot and the starter was just plum wore out. I do want to pass on an old man's observations and advice tho. Under hood temps are sky high on modern vehicles with crowded engine bays and air dams and such to try and eek out a little more mpg compared to vehicles of old. When possible do your hoses, serpentine belt, and yes the starter and alternator a favor and pop the hood to let some of that heat out, especially after a long pull with a load or trailer even if it's only a few minutes at a rest stop. I realize this is not always practical, e.g. after you've arrived at work or when you go into a store or such. I've been doing this for years, even with the wife's grocery getter, and although I can't quantify it I'm sure it has saved me a lot of maintenance costs and inconvenient breakdowns.

Are starters disposable? Serviceable? Can’t the brushes be replaced? Bearings? Etc.....

Finding a place to rebuild one is hard, it's a dying art. There were no less than five "alternator" shops near my folks place twenty years ago, not one remains.

It's just as cheap to buy a reman or even new sometimes.

For the record this truck has 165k miles and a lot of towing and daily driving year round. Starter lasted twice as long as the old 350...they went every 80k like clockwork

These days everything gets thrown in the trash and replaced.

 

For myself, I use this place alot, mostly for alternators, but you can do some starters too: http://rebuilderinabox.com
