hey, i think i have the same problem. Id hate to add onto your thread, but im also a first time poster.
Me: Bruce
Mine Also have a 90 celica Gt 5 speed
Mods: Exhaust right now, intake is on the way. Rims, low pro Kumhos, lowering springs, and new struts over the winter, as well as paint job.
OK, so anyway, i beleive im having the same problem. the is a clicking sound coming from the passenger side, front tire. It mostly happens in 3rd, around 30-35 mph, in a slow acceleration. Pushing in the clutch stops the noise from happening. I took it in t a cv shop, thinkin my cv was shot and needed work. They told me that the cv was fine and that my brake pad was loose and rubbin funny, and was causing a clicking/clunking (hard to describe in words, (sorry)) sound. Only, i took apart my brakes, and everything looks like it should, so im beggining to think its not the brakes, and it wither the drive-train or transmission.
Im lookin for ideas, and seeing as someone else has a similar problem on the same year car, is this comon??? id love to hear ideas or feedback.
