Hi, John.
I think that I had the same problem. IMHO, it may be the needle
bearings
in the half shafts. I also replaced the u-joints, only to have a gentle
"toka-toka-toka" sound come from the rear end. I noticed it mostly when I
was coasting with the top up.
I replaced the half shafts and bearings and the noise went away.
Unfortunately, I understand the problem will return sooner or later because
the inner needle bearing rides directly onto the axel shaft, with no inner
race. This wears the axel down in just a few thousand miles.
At the British Car Show last year at Chateau Ilan, I met a gentleman name
Scott Howell, who will machine out the bearing housing, add a new larger
bearing with an inner race on the axel, thereby protecting the axel from
wear. He charges $230.00 w/ exchange, I think per half axel. But it's
supposed to be a permanent fix.
He can be reached at HPImports@webtv.net, or at 336-884-1455 (High Point,
North Carolina). Of course, I have no financial interest, but am keeping
his business card on hand, just in case I hear the "toka-toka-toka" sound
again!

Subject: Clicking/clacking noises
Hi all,
I'm looking for some advice on a sound coming from the rear of our 78
Spitfire. This car was an off the from restoration, which we purchased in
PA, and had delivered to MA. WE test drove it in PA with the top down, and
noticed no unusual noises. Driving it in MA, we hear a clicking/clacking
type noise from the rear. As you accelarate, it goes away, and is much more
noticable while coasting. The speed of this noise goes faster and slower as
the cars speeds up and slows down. A local spitfire buff suggested perhaps
u
joints. Come to find out, all of those parts are brand new. Brought it to
a
highly respected sports car garage, and they suspect CV joint, transfering
noise down hollow drive shaft to back of car. They will be looking at it
more carefully in a week. Any thoughts? Car has 49,000 real miles on it.
Apparently there is no longer made driveshaft, cv joint issues.
Also, pollution air pump makes noise till car warms up. Sports car garage
says it was lubricated with teflon bushings, that wore out after about 100
miles on car! He spayed some lubricant on pump, adn noise immediately
disapperaed. Do I replace this pump? Garage says they never really did
much
to help pollution, but made US EPA happy cause it was there!!! I would
apreciate any thougts from you experts. I am new to this.
