Lift gate maintenance?
TheNekidChef
its a RAM type of lift as well as your fluid level. Be sure to carefully
inspect the power connections and any long run cable that goes to your HOT
battery. This cable might be cracked and could cause a fire rubbing against
the frame. Other than that.. ...

the fluid is topped up. Any water will have collected at the bottom of
the reservoir and the pickup tube is usually higher than the bottom. You
can always try to drain a little bit of fluid from the reservoir to make
sure that there is no water but a little will not hurt. The fluid will not
have degraded that much, unless it has been there since the system has been installed.
Do a good visual inspection of all the hydraulic lines for cracks,
blisters, etc... Check all the connections and tighten them as necessary.
Check and lubricate all bearings and tracks. Remove any dirt that may
have collected on the sliding parts of the pistons and that's about all
that's required. No bleeding is required, just make sure that there is
sufficient fluid in the reservoir.
The hydraulic lines part is the most important as it will make a mess if
any ruptures (beleive me), change any damaged ones.

it is almost certainly Automatic Transmission fluid in your electric
pump/power unit. Fluid should still be slightly red, like ATF, just buy a
dexron II ATF to top off if necessary.

Dexron works fine in most of the liftgates I see on a daily basis.
your only problem with it will more than likely be cold weather
related.. the thicker the fluid, the slower it returns back to the
resevour.... thus slower lowering. Some litgates have a variable
pressure regulator that will aid in the performance of the lift during
different weather conditions.

You can drain the fluid (not recommended) by pumping it out with a
line removed, or put the gate in the up position, with the return
linein a bucket, and lowering it...
there's no filters that I know of... at least none of the common day
models I work have them.

owners have any trouble with the tail gate lock ? My lock feels very cheap
and you only have to put the key in part way to open I bring it back and
they lube it ,like I can't.
Any thoughts on this one .Buy the way it is the only problem I have with
the truck and I have had many .I think it works with my life style
snowmobile and small trips . thanks for your time

After all, it would be a new kind of Hell to have an Avalance ( GM) tailgate
lock problem on a Dodge ( Daimler Chrysler) vehicle, wouldn't it ??? Or on a
Ford, or Toyota, or Datsun, / Nissan, or a Radio Flyer wagon.

into groups that may even be happy he's having a problem with his "Rolling

I would like to ask who the Mfger of that 1500# lift gate is, if it
were possible to read from a label anywhere on the unit.
As for restoring the rig, and lift gate, I would urge you to replace
all hoses, and cables, (especially power cables), and then dismantle
and clean the cylinders, as there could possibly be some "dirt" in
there.
As for fluid, there are several kinds of hydraulic fluids aout there,
and you can also use ATF fluid; although I dont really reccommend it.
Since we have all kinds of hydraulic lifting equipment here in our
yard, we always replace any AFT fluid we fidn with hydraulic fluid,
which can be bought in any autoparts store.
The Hydraulic fluid gives us much more controm over the use of the
unit, and is interchangeable with anything we have.
Save any ATF fluid you find, for possible use in a vehicle with an
Auto-Tranny.

Deranged,
I really don't know if I agree with this train of thought. Atf is not really
that expensive to buy and I sure wouldn't put used fluid into a trans unless
as a last resort.
Denny
DerangedDragon
Well, I agree with ya there, but if ya dont want to use it for the
tranny, you can still save it for use on hinges and such.
Yet many of the older model liftgates had Hydraulic fluid, and not
tranny fluid in them, Which is why I suggest replacing the fluid with
hydraulic fluid, instead of tranny fluid - and the cost shouldnt be
all that much different.
We get out Hyd fluid in 55gallon drums, which actually makes it 1/3
the cost, per quart, than AT fluid. But then we have more than lift
gates around here; ie Clark Lift trucks - P&H Cranes - Cherry pickers
- you name it, we might have it.
