I ordered a N54 throttle body to swap on my N52... hopefully this is worth the $67

Yeah it does lol. I think I got some satin black around here somewhere

I'm assuming that the vibration changes with load/coast?

if so, highly likely it's driveline related.
the diff will always have some backlash, and some free rotation. How much radial play? it should be very minimal. the pinion is on tapered bearings, so it should be pretty tight. Does the pinion move in/out at all from the case?

put a small pry bar between the yokes of the u joint and pry on them. If you see the yokes move away from one another, joints are wasted.

Belt time baby

Old belt

Aghhhh the clutch pulley is making a clicking noise and my tech said it doesnt feel like the decoupler pulley. Cuz they both have clutches. I hope my ac compressor pulley is not messed up

I got two huge jobs done today. First I tidied up my jack-point pads. I found an old camera lens pouch that I never use that is a perfect fit. It keeps the pads from sliding around the trunk.



Next I changed out the manky, old, yellow marker lights on the fenders for some new ones from RockAuto. I think they look much better. See before and after pictures below.

Past a milestone today...if she's nice maybe I'll wash and wax her tomorrow.

Did the side marker come with that silver bulb?

On rockauto it shows it with an orange bulb.

Yes they came with the silver bulbs.

RIP William. Hope it's temporary.

Are you sure that's the old belt?

Looks like new to me

I texted him and it looks like the ban is permanent. Told him he should try to sign up again with a different alias--his contribution to the forum on the sheer knowledge on DISA valves alone is invaluable.

I messaged him on another forum and told him the same thing. I really had no idea it was so easy to do the 3SI swap if not for his posts and videos, really got me started with that project. If they're gonna ban content like his without recourse for spurious reasons there's really no place left to go online to escape cancel culture.

They look good. I managed to polish my lenses up but the gasket is half white and half black and nothing will make it all white again.

Was the other day. Had a little photoshoot with my new camera

[colorado.e9x]

Man I really did like this forum up until Will's ban. I do agree he should either join under a different alias, IP, email etc or perhaps a large enough petition to the moderators and a well crafted "apology" note.

Agh, I just don't like the other forums; the layout is subpar, there isn't an app, and all of you guys are well, on here

All that except the "apology" part, F that this whole world can get bent if it comes down to apologizing for fake offenses. (this is why I'm no longer welcome on every major social media platform, trying to stick to cars here but it's tough sometimes)

[colorado.e9x]

Emphasis on the "". Sometimes you gotta play the cards even if you don't like em. I'd rather have Will back by means of some bs apology than not at all

Don’t really feel too much vibration or just don’t know how much vibration to expect. I didn’t feel anything else but some free play, nothing on the diff doesn’t move in and out of place. One note though - my shift lever used to vibrate slightly at idle, when I replaced the flex disc, this vibration disappeared for a bit. It reappeared after the test drive. Must be either ujoints as you suggested or, as I found in some thread, it could be the damper rings which are installed on the splines which go into the csb:

Item 5, never mind it’s a diagram for a diesel, it’s similar for n51/n52

So a bit of an update:

My driveshaft parts finally came in after 5 weeks wait for the center bearing. I replaced the center bearing and rubber flex joint (we used to call it a guibo), and the transmission mounts. The driveline got a bit smoother, but the vibration I was originally talking about was getting better as the miles racked up anyway, so all in all not a big change. The center bearing was a bit loose but not too bad. I may do the engine mounts just to be sure, and maybe the diff mounts too. I still think what happened was an internal baffle in the muffler broke back in February and was/is causing the vibration. Or it could be the diff is going, but I'm not so sure. If it does after 246,000 miles, I'll rebuild it with an LSD. I'll keep you posted on it.

Now what I did discover is this. The driveshaft has two small plastic isolators ("damper rings") that sit on the splined part of the shaft (Item #5 in the pic below). My driveshaft when I disassembled it did not have these parts in it. Being confused that it didn't, I was leery to put both new parts in (I was smart enough to order them for some reason), so I just put one in instead of two; I was concerned the shaft would not collapse far enough to reinstall it. Well low and behold the metallic clink that some of us hear when we load and unload the drivetrain has now gone away. I think these two little plastic damper rings were added to the drive shaft assembly to prevent the noise.
