Jacksonville, FL E30 fam?

[kwill22]

Know if I'll be able to go that far. Depends on a few things

[Poorboyz]

My e will be back together soon.. hopefully.
I either need a new diff, or a new driveshaft(again)
Anyone have any input? The driveshaft has about ~10k miles on it, I just rebuilt the CV axles and replaced the tranny mounts(these were in half, maybe caused the driveshaft to go bad again? the u-joints feel fine when it's off the car. New fluid is in the diff

What is the problem you're having?

I figured the drive would be nice along the beach road. Up for other suggestions!

If you're going through driveshafts is it your Ujoints? If so something is binding or stressing them. Diff mount severely worn or installing the driveshaft with tension in the joints could do it. Are you having any noises?


I'm down for St.Aug but my wife's due the 11th so i dont know what'll happen if she goes early or later so I won't have an idea until closer to that time. An A1A cruises would be perfect

1st should be fine. I'm trying to finish my m60 swap by then but I need to road tester first

I should be able to go Nov 1.

forgot to include the symptoms lol..
the problem is a vibration under load, mostly above 2k rpms. really bad vibration and you can feel it coming from the rear or towards the rear of the car.

e30 u-joints aren't serviceable so yes they were replaced with the driveshaft
also diff mount looks solid no cracks.
no noises other than what the vibration causes

[andrewm]

Sounds like the center support bearing could be failing you, very common on our cars. Symptons dont sound right for the u joints.

Additionally, I am selling my 1987 ETA

I second CSB. You didn't install it with tension on the bushing did you? I know that pretentioning the csb was floating around for whatever reason. That'll wear it out prematurely much like bolting up the guibo the wrong way. Made sure driveshaft was put together perfectly so it stayed balanced when you installed it?

[walktheboard]

The csb and guibo were replaced along with the driveshaft. I'm not sure what y'all mean by pretentioning and how to insure it stays properly balanced during install? I hope I haven't messed the new(ish) shaft up.. But it will be nice to know what is causing this

[andrewm]

the CSB's fail a lot, I always just spin the driveshaft a few times while it's connected before tightening the CSB down.

[kwill22]

When you replace the CSB you have to separate the 2 halves of the driveshaft by unscrewing the big collar nut. You're supposed to mark both sides of the driveshaft so you know exactly how it went together so it stays balanced.

As far as pretentioning the CSB. When you bolt it up some people thought that you should slide it forward so that there is tension on the bushing when you tightened it instead of just positioning it normally without any tension.

[walktheboard]

Yeah I made sure the side went together the same way they came apart. No I did not do the pretentioning procedure, I'll line it up with some string to ensure that it is straight from diff flange to trans flange when I get back in town
Thanks for the advice!

Anybody going to cars and coffee tomorrow?
