Hey guys im looking at buying a 88 N/A and when i shift hard from first to second it doesnt like it too much.. It grinds real quick sometimes and makes a clunk from the rear.. any ideas? it has a new clutch.. i was thinking tranny mounts? any idea's and how much am i looking at ??

spunks

U-joints are shot.

A clank when taking off is the U-joints. A clunk or thump while on/off the gas or clutching in/out will probably be the read differential mount.

How exactly would you fix it if it were the rear differential?

You go and buy a new mount and put it in.

I think it is your suspension frame hitting you subframe
i had this when i used a rear camber adjuster and set it a little too low

i dont think so tho its only on the shift .. seems like only hard shift first to second..... any ideas... ive heard bearings bushings.. trany mounts ... but i dont know how to tell or how much any of this costs

If you have access to a lift....get car up on lift and with someone in the car have them engage the clutch with the e-brake on....being under the car you can see if its your mount and or drive shaft. If you don't have access to a lift.....then if its only doing it in 1st to 2nd on hard shifts......id say it might be your drive shaft is starting to go.

Clunking with lower gear shift is usually the front U joint, in higher gears the rear one. FYI, if it is the U joint(s) you will have to replace the entire drive shaft. The U Joints cannot be replaced in the stock drive shaft. Just replaced mine. The shaft is 325.00 from Mazda.

i had the same problem as mr_vaughn said. but it sounds like that could be it but could be u-joints or the diff mounts as well
