80 series shudder / vibration on acceleration

[Squash]

Just finished this kind of issues a few days ago.
1995 1HD-FT
Noticed some vibes from the ashtray, check for the usual suspects like coins, small screwdriver or 10mm.
Came and went on acceleration or decel.
Decided to pull both driveshaft spline zerks, spray some brake cleaner into zerk fitting, and then drive. This especially for the rear normally works...reinstall zerks, grease rear, while greasing the front I found the culprit.
All 4 front D/S nuts were loose!
Silky smooth once again.

Thanks…this is what I’m looking for. I will plan to do this sometime this week. I did yank in both driveshaft and felt nothing to be loose, but could be dry. Thankyou again.
