More MAR aftermath

So on the way home what seems to be the rear end is vibrating pretty good, it lessens some when i put the clutch in..

symptoms: pretty good harmonic shaking when decelerating from any speed over say 35 mph..

it does shake a lesser amount when accelerating but not as bad..

Driveshaft loose? Clutch going (slipping? doesn't feel like it..) something else loose back there.

My steering wheel does not shake so its not death wobble or maybe it is.

also getting a CEL 45 again (started on the fire roads before the alt went) that is now constant. Only Code 45 is present when i run through them, I did find that my o2 sensor was loose on that side however tightening it up and switching to a backup did not change the issue. I'm going to retime it tonight if needed. which fixed this they last time. and check the exhaust bolts on that side.

The good news is the Alternator works perfect, and i have a 140 amp one on order

ah the joys of rover-ing

its a 95 D90 NAS for guesses

Time to start checking for loose nuts and bolts from the wheels, driveshafts to transfer box etc.
Doubt its a suspension related issue, but check those anyway.

No spacers, checking wheel bolts as we speak

Rob, also check the back side of your wheels.
You're running the boosts right?
Sometimes even when the front looks pretty clean some mud or clay will stick to the back side and throw off the balance significantly.

Bad U-joint in rear prop shaft. Worn bearing on t-case output or diff? Shake everything hard and see if anything has any play.

Or built up mud in a wheel. ;-)

Mud in the wheels was my go to.. I'm probably going to need to pull them and double check.. But that would make it vibrate coasting too (it does but not nearly pronounced as it does in gear which has me worried

Think I found it.. Rear u joint looks like it has 1/4" of movement in it.. That would explain the driveline vibration under load I think... Easy to replace? The whole rear shaft has some play as well.

Related question, while I wait for a u joint (unless I can buy one locally) can I remove the drive shaft and run in front wheel drive? Diff locked?

Yes, but will promote tire wear on the front wheels.
UJ is a universal size shared with many other marques.

Thanks Robert picked up a spicer one locally (or at least made by spicer supposedly.
Looks like an easy install
Drop rear of axle, remove and replace, fill with grease, reinstall axle bolts on rear. Am I missing anything?

If one end is gone the other is soon to follow, you say the whole prop shaft has play? Is there any up and down play in the sliding coupling?if that is loose as well, get a new prop shaft.

no problem driving on the front if the rear DS is out or vice versa. It won't affect tires at all.

Yeah, don't get tire comment either-- no big deal to run without drive shaft. Also, uj's are super easy to replace and frankly just replace worn one. I know which ones I've replaced and which ones I haven't and I have one that is amazing (3 to one, rear on front drive shat). They don't wear equally not do you grease them equally. Some caps plug and don't get fresh grease and wear diffrrently. I replace what needs replacing...

Chris, if one doesn't take grease, tap the opposite yoke with a hammer to push the spider over and make more room for the grease to get through.

Thanks all - I just got one.. so will report back - i may have to outsource the job (along with chasing the CEL 45) as its my DD and this week is packed with after work Kiddo stuff..

Drive shaft does not seem to have up/down play - just rotational play if that makes sense - front has the same slop.

I'm probably going to need to gets some wood(s)
