2nd Gen Non-Engine/Transmission Still Shakin’

[wilsonsh]

i meant where do i connect the timming light. i only know #1 spark plug wire

I will be replacing the rear DS u-joints and getting another alignment and maybe get the tires rounded if I can.

Yep, timing light isn't really an option here! Like I said, you can look at the marks and the overall condition of the damper but that's about all I know... .

 

[BEnglish]

Well I changed out three perfectly good u-joints last night and no change.

I just dropped it off at the alignment shop to get another alignment. I think it has gone out with the changes I have made.

I also asked it they could find the shake and they said they will look. I am not holding my breath.

I also asked if they could make tires round, they said no but told me there is a place somewhere close but I will have to look it up. Is this a good decision? Do they do it on the truck or do they take the wheel to a machine?

I got my wife to saw the steering wheel back and forth as I watched for movement at the linkages. I saw my new SS 3rd gen adjustable track bar moving at both ends. I added this to eliminate the movement and now it moves at both ends. The bolts are tight and not moving. It is the rubber in the ends and it is moving pretty bad. I took it to an alignment shop and the guy said he wouldn’t align it till that was fixed. What gives? I thought this would be a better set up? Is there a polypropylene bushing set I can replace the rubber with? What has everyone else done about the rubber?

Wow! That is very bad news to me. I also expected the 3rd gen bar to have no movement on either end.



I will be watching this thread very carefully.



Try calling whoever you bought it from and maybe they will replace it as a defect. Keep us informed.

I did not see if this was posted as a solution, but I had HUGE shaking issues, I did some deducting, as to what has changed and it turned out to be, Brake Drums in the rear, the new out of box replacement drums, were not balanced at the factory, if never checked until, they just about shook my dually loose, then I checked, and replaced/swapped them for new upgraded ones, and NO MORE SHAKE.



Don't underestimate the most simple things.



Brake Drums... . ????

how did you test them?

 

[therobzilla]

When the shaking showed up, I went back with a friend and replayed everything that had changed since the shake appeared.



My friend is a M. E. for Honeywell, and works in getting vibrations out of turbines and extremely small and large parts. I took him for a spin, and he knew it was not driveline because of the pitches of the vibration, and in his very M. E. style, we started reviewing what had changed.



He told me since the only thing that had changed major since it showed up, to check the balance of the rear drums, I told him in my very UN M. E. style he was full of it, as the drum that were just put on during my rear brake rebuild, and I told him they were right out of the box from the parts store.



He bet me a case of Mexican Pacifico Cerveza that based on the vibration pitch/type of vibration, it was the drums.



I marched down to Napa the same hour and plunked down 300. 00 for another set of PREMIUM rear drums for my truck.



I jacked up the rear, grabbed the drums, and proceeded to replace on side, the first thing I noticed with the new replacement premium drums from Napa was that they both had very large semi circle weights welded to the outside of the drums. I knew at that point I was going to owe him a case of beer.



I took both wheels off the rear axle, and the first thing I noticed with the old/replacement drums that I just put on during the brake job, was that they DID NOT have the semi circle weights welded to the drums. At this point I knew the problem was the drums.



I replaced both drums with the new Napa Premium ones with weights welded to them, bolted the wheels up, and jumped in to take a spin.



GONE!!!! Rode like off the factory floor. Dug up my receipt for he older drums, brought them back, got my money back, then proceeded to drink the beer I owed him, over a BBQ in the back yard.



DRUMS??? Go figure. My shake and bake is gone... ...



Just my experience. Hope it sheds some help on the process of figuring it out.

I have seen the "weights" break the weld and fall off the drums.

 

[95REDRAM]

Interesting. I still have the factory drums and they have been turned once. I figure a proper turning should not change the balance but who knows if they were done correctly? I did do the rear brakes about the same time my vibration showed up but it has been too many years to remember for sure. I think I'll look into this idea a little further.

Oo. IT’S FIXED!!Oo. !!!!Oo. !!!!!Oo.





It was the drums.



I want to give your friend a big wet kiss on the face!

I had already thought about them, but thought no way.

Now that I think about it, just before I got the truck the PO had done a break job with new rotors and drums, the whole nine, but he must have gotten cheap drums.

I just didn’t put it together till I read your story and then as a last resort I went down to have the tires “road pressure balanced” where they put a load on the tire as it spins.

On the way home same thing, no change.

So I said what the heck I will try the drums, I have tried everything else.

So like you I got the Napa premium drums about three bones.

And just like you when I started comparing the old and the new no weights on the old and big ones on the new.

Took it down the highway and because of traffic I could only do 75, however that is well out of the previous range.

On the way back I got it to 85 and smooth as silk.

If I wasn’t so manly I would have balled like a little girl. Oh who am I kidding a tear might have come out accidentally.

Wow! You sure went thru alot to get that front end wobble fixed. My hats off to you... and thanks to you TDR guys. Bad BRAND NEW Drums... go figure. I'll remember this one, especially if the drums need replacing mine will be NAPA. I got a quote from NAPA of $110 each.



By the way... earlier you mentioned a lot of slop was found in your new SS 3rd Gen track bar. Thats's the same track bar I have and I didn't expect any movement in it. I'm concerned this could be a front end issue. Anymore feedback on that?

I got my wife to saw the steering wheel back and forth as I watched for movement at the linkages. I saw my new SS 3rd gen adjustable track bar moving at both ends.

Yes it moves at the bushings, more than I think it should, (I am not a pro) and the guy at the alignment shop said the same thing. He said they wouldn’t align it because of two things, bad ball joints on drivers side (only had about 1000th movement) and too much play in the track bar bushings. Well I changed the ball joints today and I still don’t know what to do about the bushings. I cant remember now if the bushings are rubber or polypropylene. And I am not sure if there could be another reason they are allowing as much movement as they are.

I started this thread because of the shake. Along the way, as long as I was replacing parts, I also wanted the steering to be tight and true, and I kink of figured the two were related. Well in my case they weren’t.

I will still continue to improve the front (I just ordered the rock solid steering column/shaft bushing, and I will see if the track bar bushings can be traded out for stiffer ones, and to tell you the truth, there is too much slop in my new PSC steering box, about a tenth of a turn between the input shaft and the sector shaft, and I am going to see if it is normal) till I get it just the way I think it should be. But I am soooo happy because to me the shake was almost a deal breaker. By far the most important problem. It was no fun to drive. But that is behind me now. So I’ll just keep on the steering till I get that too. I will keep everyone informed as I make progress. Thank you TDR.

I'd get on the phone with PSC and discuss it with them. These PSC boxes are rebuilt not new but they do stand behind their product. I'll have to check my PSC box and 3rd Gen bar too.



Does the truck seem to steer and track ok with those 2 problems?

Its plenty drivable (especially as smooth as it is ) but there is a dead spot in the wheel and I have replaced a lot of things in the front since the last alignment so it isn't tracking great. I do have to saw the wheel a bit to keep it in the lane. I will get an alignment ASAP.



Oh, and I am going to call them as soon as I can. I tried on Wednesday, but kept getting a busy signal. I have heard nothing but good things about there policies and have already had good customer service. And who knows, I may be way off base and that amount of play is normal? Any way I will call them tomorrow.

 

[therobzilla]

Very good to hear that your shake and bake is gone! Congratulations.



I thought it was a shot in the dark. I don't normally post up much, due to the fact that I learn more from reading, than I could ever post or offer to others.



I'm mostly a lurker. I have gotten WAY more from this site than I could ever pay back. I'm glad my comment helped.



Maybe we will see you on the trail some where sometime.



Wheeling is cool, and VIVA PACIFICO!!!

 

[BEnglish]

and to tell you the truth, there is too much slop in my new PSC steering box, about a tenth of a turn between the input shaft and the sector shaft, and I am going to see if it is normal.

I would like to apologize for saying this… As it turns out the collar on the end of the shaft that attaches it to the input for the box was not tight enough and had some play. This was totally my fault and I would not want a great company like PSC to get a bad rap because of something I said. They are great products and great people.



and by the way my steering is fixed now to so i am 100%Oo.

Ben, great thread and thanks for letting us know about the solution( and thanks to the fellow who clued us in on the drums). I need to replace mine(long story, dummy that turned them got them out of round), so I'll look for higher quality ones when I do.

I'm curious though, did you ever replace the 3rd gen track bar? Was the play within spec? My brother put a Thuren Fab bar on his truck and it is amazingly tight now(also has the complete tie rod set from Thuren).
