Default 'Thud' in the Rear...

OK...so, just about every other time i come to a complete stop it sounds like i had my bookbag in the trunk and it rolled over, im not stoping hard...but i tried that and i heard it once of the two times i did...

Nothing is rattling during the drive, i got up to 80mph with the traffic on the interstate and felt nothing unusual, turning is fine so idk what it is, other than something a little losse, any idea what it would be guys?

If you get the thud when taking off too, check the gas tank straps.

i don't recall hearing anything at any other time other than stopping...

but i could probably check that anyway, but college applications have me kinda tied up, and the cold is very discouraging

A few things to take a close look at might be rear body mounts, control arm bushings, stabilizer end links, stabilizer insulators, shock absorbers.

based on further driving...would the e-brake be able to get stuck..or not completely release?

and thanks for the tip

Yes, that could happen and an easy way to tell which side is to feel the temp of the rims. If one side is hotter than the other than thats the side witht he stuck brake.

Well, bonnevilles don't have trac(k) bars, so I don't know what you're talking about there.

I suspect your rear brakes are fubar. A close inspection with the drums off is in order.
