Can e-brake cause a vibration ?

[philo_beddoe]

Is this the one we can trade, how do you adjust belt tension?

PS pump bracket update.

After being down for a week and a half, and money, time and sweat and agony (yes over a stupid ps pump bracket), i took it to a place i knew and had it welded back together for free. The top mounting tab broke off, the large triangle shap left mounting tab was missing all along, thus a new one had to be fabricated. Oh, and they threw a coat of paint on it.

I know there are many applications and sometimes after market parts work. But generally, i hate aftermarket. And no disrespect to those that have custom trucks and engines and such. Nothing beats OEM, they always seem to line up nice, fit and be correct. IMO.


Ps. It took less time for Vile to put a whole new engine in my truck! Good grief! Oh well, this job is done. Next!

More update:
Yup, as i suspected, the fixed up bracket (oem specs), lined up perfectly, and i didnt need a stack of washers to line it up, only a couple. And....no more driveline vibration, that was the culprit all along! Truck drives real smooth.

Good job

[philo_beddoe]

Thanks man! Appreciate it. I was never worried a bit nor had any doubt. Lol!!

[philo_beddoe]

Perhaps i jumped the gun. Well the ps pump is perfect, pin straight and true. However, on the way to work i did notice the slow pulsate driveline vibe. Not present when reving in park. Weird though, as before, i mostly notice on the way to work, but hardly on the way home. I wonder if it could be the front u joint, a little sticky perhaps? I think if it were anything else it would be uniform and continuous, at all times.

What's the difference in ambient temperature between your morning and afternoon commutes?

[philo_beddoe]

Could that possibly make a difference?

Are you sure you don't have a tiny separation in a tire?

[philo_beddoe]

What do you mean "separation in a tire?" Tires are new, vibe is only under load, accell and even decel.

A while back i did have that leak coming out the weep hole. So i plugged it. Wondering if this could be worn tranny tailshaft bushing, thus tranny output shaft seal. Perhaps incorrect front u joint? But,,the problem is not constant and uniform 100% of the time.

[philo_beddoe]

May have broken ground, actually noticed a vibe on the way home, so i stopped and gave the front of the dshaft a couple of light hits with a hammer, after that it drove smooth as glass. May have freed it up, but will probably go back after changing gears a few times.

When i changed u joints a month ago, the ones i removed were different makes. I put in nice spicer brand, same part number. However, the front was a little sticky. The rear was nice and smooth. I may just have a shop balance it out anyway and even change slip yoke and get the right ujoint on there. Unless the vibe never comes back....which i doubt. But being a sticky ujoint i guess would cause it not to be the same and continuous all the time.  Thus, chaiging gears (DFR) would change its dynamic, more free/sticky.

Does this all sound right? Normal?

I wonder if the ears of the shaft were bent a tiny bit-this will put excess pressure on the u-joint and cause it to be tight and also wear faster. This is why you place some sort of object between the ears when pressing the old joints out.

Good point, i wonder too. And if so, it happend before i took ownership. Regardless, i'm having that bushing and seal done, and at the same time getting the dshaft balanced and have that rectified. I'll mention that at the dshaft shop.

[philo_beddoe]

Well ever since i tapped the front of the dshaft with a hammer, its been real real smooth. I hit it at the yoke. Could the ujoint have been sticking or frozen? Its smooth 100% of the time. But im not holding my breath. At least i broke ground. Figuring out a vibration is like solving a big case.
If it comes back, will try new slip yoke and ujoint.

maybe not frozen but maybe was squeezed too tight?
