This is a PM from cinquecentoe,

Hello there,

I am trying to find help, but do not know how I can
send a message to the forum so that anyone can read it
and help me with these vibrations on my 1990 K5 Blazer
4x4 .

I saw that you must have one, o.k. a 1991, which I also used
to drive, it was a GMC Jimmy, which lasted for more than 132
000 miles before I sold it.

Maybe you could give me some advice how to send a message,
thanks for your help.

Regards

Alex

Alex,
Welcome to CK5!!

If I understand your question it is easy to make a post.
from the board you want to post to, select 'POST' in the upper right corner of the blue part of the page

Based upon your question about bad vibes in a 90 Jimmy, I would start here http://coloradok5.com/forums/postlist.php?Cat=&Board=blazer4x4

Put something in the 'Subject' area
Put the details of your question in the Post area
remove the check mark from "I want to preview my post "
click on 'Continue'

That should get you a topic posted /forums/images/graemlins/cool.gif

All,
Anyone out there fluent in German that can add to this? Hopefully I didn't make too many mistakes - forum and cultural /forums/images/graemlins/ignore.gif

Non-paying memebers can still post here I hope.... /forums/images/graemlins/blush.gif
 
Sounds like he doesn't have Cookies enabled. If they are off it won't let you post.

As for his problem. If the truck is not lifted I would start with U-Joints failing.
Need to know any modifications (lift and type etc) before we can go much further.
 
Gibt es ein Problem mit Erschütterung und Ihrem Blazer? Zuerst erklären Sie uns über Ihren LKW-Aufhebungheber und -getriebe. Auch, wenn Sie sie anhoben.
 
Thanks Guys. Both good suggestions (I think, LOL).

I hope he is looking.....

I replied to his PM with this link.
 
Me thinks that you just nominated yourself for the German CK5 translator posisiton LOL
 
OK,
He has the PM part down! Here is his question:

Hey Dave ,

thank you for your assistance to get my questions to the forum.

All,

hello everybody, my name is Alex, I am 42 years old and
a fan of Chevy Blazers since the 1970 TV series "Colt Seavers" .

O.k. , now lets come to my problem. My 1990 Chevy Blazer is
in standard condition, no lift, no extra wide wheels. I run
the vehicle on the following tires:

- 31 x 10,5 x 15 on factory rims 8 x 15
- dito on factory aluminum wheels with these
holes (option on model 90 or 91)
- 235/85 R 16 handmade spoke wheels 8 x 16 (??)

I do not choose wider wheels as the gas price here in Germany
is about 4 $/Gal., yes 4 dollars a gallon !!! You can
imagine that any effort is made to keep the consumption as low as possible, therefore no cherry bomb etc.

Now, I experience these often mentionned vibrations in the
driveline, starting only at the speed of 65 mph, which sound not that bad when you change the U-joint of the rear axle. After the change it takes about 2 - 3.000 miles when everything starts all over again. I use U-joints TRW 20040 with grease nipple. Do you recommend other type,brand name ??

I also had the front and rear driveshaft balanced, rear axle
bearings and carrier overhauled. No improvement. In the last
weeks I invested an overhaul of the gear box, done by a specialist, who held a record in the U.S.in 1/4-mile-race for 7 years,with a selfbuild garbox and a hemi. . . engine. He changed the gearbox from 5 to 9 clutchplates (?) and the gearbox is run with DEXRON III now. He also put a new torque converter in which is fluidbalanced.

Still these vibrations. We once tried a test drive without
the front drive shaft, than we had the impression that the
vibes come from the front and not as usual from the rear axle.

Could it be the "self locking hubs" which maybe need a
cleaning and regreasing ?? Maybe they engage at this certain
speed of 65 mph (underneath that speed no vibes !!)

As you have more experience over the years maybe you have the
correct answer to my problem.

Thank you in advance. I hope my English is good enough so
you understand my problem.

Kind regards from Germany

Can the German speaking folks PM him and give a better explanation on how to make a post? His english looks good so it is probably a cookie issue or bad instructions from me......
 
Get rid of the auto hubs. They screw up all the time. A quick test would be to remove the locking hub and front driveshaft and take it for a spin. Paved roads so you don't get dirt in the wheel bearings.
 
I had the exact same problem with my '88.
I tried everything, even had a new driveshaft made.
It would go away for a while and come back.
It always happened around 80-100kmph, and only when coming off of a coast situation into accelleration, the vibration was not even noticible under load. Well to make a long story short, after seven years of throwing money at it, I decided to completley rebuild the Blazer. pulled the motor out last month and both motor mounts were shot. I'm sure when I put it back together my vibe will be gone. /forums/images/graemlins/blush.gif

I agree that I think he can understand what we're saying okay, based on how well he writes, but if there is anything you'd like me to tell him in German, let me know. I'm a fifth semester German student and will try my best.
 
I gave him the link to this post in a PM - kinda confused as to why he has not answered here.....

cinquecentoe, are you out there?????
 
Vibrations starting at 65 mph on a 1990 Blazer GERMANY

All,

I hope I finally found the way to make a post in the correct
manner.

Here again I would like to ask for help with my 1990 Blazer 4x4, which is in standard condition, no lift, no cherry bomb
etc. Standard wheels 31 x 10,5 x 15 on MICHELINs 4x4 AT .

I experience vibrations only starting at the speed of 65 mph
with acceleration or cruise . I had front and rear driveshaft balanced, carrier and bearings exchanged, new tires . . . no improvement.

The only improvement occures when I replace the rear U-joint,
but it only takes 2 - 3.000 miles when the U-joint gains side
play again and the vibrations start getting worse and worse.

Someone told to turn the rear axle so far that there is no more angle left between driveshaft and differential.
Or someone of the forum mentionned that it could be the motormounts ??

What do you recommend to check first ??

No hazzle with translating into German I guess my English
is good enough to understand even some of the difficult technical expressions.

Kind regards from Germany

Alex

Re: Vibrations starting at 65 mph on a 1990 Blazer GERMANY

From what you describe, I would say either the U joints you're putting on are not the greatest quality or they are not being lubricated before being put on.
Grease is the life of U joints and if they are not greased, you're lucky that they last 3000 miles.
I can't think of anything else considering your circumstances.
