2005 GS Endura truck battery

[pawpawlang315]

The truck battery in my 2005 Gulf Stream Endura 6340 Diesel will not hold a charge and will probably need to be replaced. I know the battery compartment is behind the passenger door step and directly under the passenger seat. Can anyone give me tips on how to access the battery holder so that I can get the battery out to get it checked.

Any advice will be appreciated.

Thanks guys. Maybe it is not as big a project as I imagined. Your explanations and the drawings really help.

Here are drawings of the step.


Hex size is 17mm I think.

If you look under the step, there is a large bolt on the front and rear of the step(7/8" if I remember right). The bolt will be towards the edge closest to the step. Take the bolts out, then you'll be able to pull the step out. You may have to lift just a little to get it to start, but once it starts it slides out very easily.

If you haven't pulled the step out before, the bolts may be pretty tight, so don't be afraid to put a little arm into them.

One thing I found out putting the step back in, the battery cable may prevent it from going all the way back in easily. Just reach up and pull the cable forward a little when you go to put the step back in, it may want to tuck under the edge in the back of the shelf when you push the step in.
