This video was intended to go over door strap maintenance, but ended up being a continuation of the previous power window repair shot a couple of weeks ago. …

Thanks for this video. I’d like to finally get started on replacing
regulator jaws in an ’87 300E and repair/replace three console window
switches. Can you reveal your source for the regulator jaws?ο»Ώ
What issue are you having with your 420?
Too harshly? They paid for a Steak dinner and got egg and chips…haha!!!
This video is just plain Excellent! 10/10 You’ve proven yet again why in my
25 years of motoring I have never once taken any vehicle in my ownership to
a garage for repair or service! I have also never had a roadside failure of
any kind! Those repairs were in the vehicle service history. I really hope
it wasn’t done by a main dealership? If that were the case I would be
straight on to Mercedes! They wouldn’t tolerate it! Keep up the great high
quality repairs! You are a Pro! π
It’s actually a 2006 model, so it’s not quite as powerful as 465hp. It has
a 6.1L Hemi with 425 HP and 420 Ft./Lbs. of torque. All bone stock and all
original. It’ll get on down the road, but not like a BMW M5, Corvette ZR1,
Porsche 911 Turbo, etc. I like the duel personality of having a stylish
four door for “nights on the town” but with 6.1L of Hemi whoop-ass for some
quality alone time on a lonely road. π
I’ve had the same issue with those switches. They are very simple and
rebuildable. If you pry on the side of the switch, the rocker part will
come off giving you access to the springs, ball bearings and contacts.
Solvent will clean out the old grease. I believe I used brake cleaner and
q-tips. The contacts can be freshened up with a pencil eraser. Then place a
small dab of electrical grease on the internals. The cover snaps back on
and you have a rebuilt window switch.
I’ve noticed what you describe with these switches and very much wanted to
attempt to take them apart, but time ended up being a factor. So I went in
with new components. I’ve kept the old switches and will likely attempt
what you describe so I can have some spares. I’m always interested in
finding the root cause of various failures.
I would definitely replace the timing chain if you don’t think it’s been
done. I think these are interference engines, so a thrown chain could
damage the valves and pistons. If you do this, also replace the guide
rails. Good luck with your 560. I hope it gives many more years of service.

WHOA that is a fast– and expensive– car! A cursory search says 465hp!?
Sub 13 second 1/4 miles!? Whats your day job?
I tend to do videos of stuff I already need to repair anyway and I haven’t
had to repair the front windows. However weather permitting, I’ll at some
point take the front door panels off and lubricate the door check straps
and window mechanism and repair as needed. I try to do that every five
years give or take.
Another good repair job. While watching the other video you did on the
window repair, I thought about fixing a problem I’m having with my power
windows… I’m still thinking about it, lol. Another reason some people
seem to do repairs like this is they only plan on keeping a car three or
four years, until something new comes along. It looks like you’re planning
on keeping this one a while. I bet that it will last at least twenty more
years with the care you’re giving it.
Oh yes, I plan on keeping it until the wheels fall off! This “shake-down”
phase that it’s in is a period of time where I can rid the car of the bad
repairs, the “contamination” if you will, and get it back to OEM
specification or better. Good luck with your power window repair. π
Thank you for the grease suggestion. Since the power window video I
addressed, albeit temporarily, the front wheel bearing/brake dust issue.
The root cause was that the carrier oil had separated from the thickener in
the grease, becoming better able to escape the grease seal. The grease
doesnβt appear to be high quality. I repacked the outer bearing with
synthetic grease and will clean/repack both inner/outer when weather
permits. The new Pagid pads took care of the brake dust issue.
have you done any of the front ones yet or is it the vid and i missed it
already did a rear
That car, which I have yet to make a video of, is a Chrysler 300C SRT8. I
like “sleepers” and that car is quite the sleeper. It comes in very handy
when you desire to arrive at your destination rapidly. π
Those “repairs” were actually performed by a reputable local independent
Mercedes/BMW repair facility. I must be careful and not judge them too
harshly because they may have offered the customer two options for the
repair and it may very well have been the customer choosing for the cheaper
fix. Either way, it pays to repair things to OEM specification and do
things yourself. Good on you for handling repairs yourself on your vehicles!
Where did you buy the window regulator jaw?
I have been asking to help me on my 420 sel
I own a 560 SEL and I also done this repair too. I hope you`ve noticed that
the car has a leaky wheel on the left front side. I suggest you change the
grease on the front bearings with the OEM grease or with Castrol LMX green
grease wich is the same as the original. Theese greases doesn`t melt down
when the rotors are hot, speccially on hot summer days. Anyway, you have a
great W126 and I love that good condition on the wood wich I didn`t had
that luck with. Keep up the good work!
Haven’t heard any reply from u
