comatosellama Posted June 25, 2015 Share Posted June 25, 2015 I have some ugly half shafts back there, could that be it? Just really hoping I didn't somehow bust my rear diff. Back of the car just vibrates like an out of balance washing machine. i'm not moving more than one or two, but the vibration feels like it should be going 70 Quote Link to comment Share on other sites More sharing options...
DaveT Posted June 25, 2015 Share Posted June 25, 2015 Sounds more like drive shaft to me. It spins way faster than the wheels. Quote Link to comment Share on other sites More sharing options...

TomRhere Posted June 25, 2015 Share Posted June 25, 2015 The driveshaft spins anytime the rear tires are rolling. Have had a few go bad on the BRAT's I've had. Easy replacement. 1 Quote Link to comment Share on other sites More sharing options...

rdweninger Posted June 25, 2015 Share Posted June 25, 2015 Tru 'dat. Driveline U-joints. Just heard the same sound from EA82. Diagnosed my boy's car in 5 seconds. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted June 25, 2015 Share Posted June 25, 2015 EA81 u-joints are easy to replace. EA82 u-joints are a Royal Pain In The Arse to do........ Quote Link to comment Share on other sites More sharing options...
rdweninger Posted June 25, 2015 Share Posted June 25, 2015 I did my research and, yes, ea82 ujoints will be a challenge. I am considering a driveline shop in Portland ... but there's no fun in that. My boy's car was easy. Remove rear driveshaft. Pull rear driveshaft from $100 parts car (she keeps giving, and giving and giving). Install new old driveshaft. But now, I want a replacement spare for my '85 ea82 wagon. So I gotta fix the broken one. Thanks, Dad !!! Tom, can I buy any ujoint for the ea82 ... or is it a special ujoint for replacing staked oem's? Quote Link to comment Share on other sites More sharing options...
l75eya Posted June 25, 2015 Share Posted June 25, 2015 This happened to my gl recently. I took the drive shaft out and the front u joint was very stiff. I used a ton of pb blaster and worked out all the dirt, the whole time rotating the joint through its movements. A bunch of mud and dry dirt came out of the joint. It steadily got more and more loose and eventually it felt fine. Put it back in the car, shaking gone. Quote Link to comment Share on other sites More sharing options...

Will any ol u joint work? Got some out in the old garage from back when we had a beat up f150 Quote Link to comment Share on other sites More sharing options...
ihscout54 Posted June 26, 2015 Share Posted June 26, 2015 These u-joints are specific too nissans and subarus of the era. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted June 26, 2015 Share Posted June 26, 2015 (edited) Got the EA82 u-joints thru AutoZone. 2-0430DL is the part number. edited to add p/n Edited June 26, 2015 by TomRhere Quote Link to comment Share on other sites More sharing options...
aba4430 Posted June 26, 2015 Share Posted June 26, 2015 Advance has a couple of options for the 87 Brat, reasonable prices. Autozone is showing a greasable Duralast for ~$7. Quote Link to comment Share on other sites More sharing options...
