I found a small bolt which seems to do nothing in its place...
Passenger side half shaft, the longer one, has a bearing.
The bearing is secured in the bearing mount with a snap ring.
On the bottom side of the bearing mount there is a bolt,
maybe 15mm hex head and 1/2" maybe 3/8" long, which
screws up into the bearing mount, but it is too short to touch
it the bearing itself. When I removed the shaft and its bearing
and feel the place where the bolt was expected to stick out
I could feel a deep hole, so the bolt was far, far to short to
make any contact with the bearing...
What is this bolt for? Is this some kind of grease point or what?
A mystery it is. I know that everytime it is removed it should be replaced.
Although to get another one it has to be a kit. Much more money than a
simple bolt ..
My question is that if it is worn what does it prevent ? I'm quite sure
there is knull marks on the bottom of it. I would like to find out
everything there is to know about this bolt also.
I made a mistake and took it out & sprayed grease in the hole. I don't think
I should have done that.
Kinda long didn't want to happen,
I had saved an online manual for the camry. Some how it was deleted, taken
away , I can't find it any longer. Would have sent a link.
That is where I found that it needed to be replaced. Everytime it was to be
removed there is a torque for that bolt . It needs be replaced just like an
The reason I had looked into it was that,
I was getting a vibratation that seemed to be coming from that area. Took
out the bolt sparyed the gease, Tightened somewhat tight , it hadn't changed
the vibration any. So I loosened it quite abit & the vibration went away ,
not totally but alot. So I had gone to the dealership they couldn't even
find it on the parts screen. Went to the parkinglot showed him that it does
exist , other than a kit of some kind that was to much money , to replace a
I think that the bolt holds the bearing race from spinning within the
carrier & that it needs that torque to do it. To tight = vibration To
loose= spinning of the race.
There was thread remaining under the hex head, so yes .
Thats my theory.
Well, funny I read your message this morning...
I found the service manual and printed some diagrams showing the bolt.
I went to the local toyota dealership to get the bolt - the guy in the Parts
could not find it on the diagrams on his computer either...
To my surprise, we called a technician Jose who is there to do such
driveshaft replacement according to the service front desk...
Mr Jose looked at my printed diagrams showing the bolt then looked
at me with a blind eyes leading a way to an empty brain and shrugged his
arms... Almost like "Why the hell I would know, I am a gardener trimming
bushes here for the God sake not a certified toyota mechanic!" :-))))
So either they were not interested in helping me with this repair - which
is quite likely, it is them to benefit for me messing up my car :-) Or
that particular toyota mechanic was not that bright and is might be
a good idea to never bring my car to this place again :-)
I plan to visit another toyota place and keep searching for this bolt.
In the meantime I will loosen it, just in case it deforms the bearing.
Just before installing the bearing I put a slight coat of threadlocker
on the outercase of this bearing, so the race should not be spinning
even without this bolt in place.
It is still a mystery to me HOW this bolt is tightening the bearing...
Mine is definitelly too short to touch the race.
According to the free repair guide on Autozone, that should be the
bearing lock bolt on the bottom side that holds the bearing in the
holder. After you remove it, the snap ring holds the halfshaft at the
See excerpt below:
14. Remove the right halfshaft from the transaxle as follows:
1. Remove the bearing lockbolt. The lockbolt is located in the
center of the halfshaft, near the dampener.
2. Using snapring pliers, remove the snapring and pull the
halfshaft from the transaxle.
So I am guessing the halfshaft was already removed in my car
by the previous owner and somebody put the wrong bolt there...
Mine is too short to make any difference in the bearing seat!
BTW - is this really such a good idea to put any pressure with
a pointy object like this bolt on the bearing???? I am quite stunned.
Anyway - my halfshaft bearing seems to be hold in place by the
snap ring alone now... the bolt is there but it does not do a thing :-)
I hope I am not asking for any disaster to happen...
I wonder if the proper bolt was used on the holder, while a bolt for
the holder was used on the bearing???
And true, if the bearing is held in place by the snap ring, I don't
know why there is a need for a bearing lock bolt. Or less vibration
without the bearing knocking around in the close-tolerance holder?
Many halfshafts are held in by a circlip too. I dunno, it's anyone's
I am surprised the Toyota guy knew nooooothing.
Not a grease point, no. It is a friction bolt designed to stop the
outer race of the bearing spinning along with the inner race on the
half-shaft. It doesn't really retain the bearing as such but does
support it in the housing, which is halfway along the shaft. At the
end of the bolt in the housing there is a plastic plug which bears
onto the bearing outer race and that should be in there, so check.
All very mechanically crafty, so make sure you replace it OK
I am surprised myself and I am not sure I would bring any toyota there
The original driveshaft was there 13 years and my friend mechanic I was
doing the job April had to jump through hoops to remove it. He was heating
the old bearing, pounding on it, eventually had to cut the driveshaft in
half just to take it out of there. We were both not experienced in this kind
of thing. It is possible that the plastic end of the bolt was lost and now
there is a steel bolt with a empty hole in its tip, which is too short to
touch the bearing.
Last weekend, when doing struts, I noticed that the shaft put there April is
torn and grease is coming out. So I replaced it using lifetime warranty and
put the new one there, but this bolt was still a mystery to us.
Now I know it has to have some plastic end... Currently it does not have
it... must have fallen out or something.
The problem is that I am unable to buy the new one - parts counter diagrams
on the computer do not show this bolt for 1995. And the parts guy is
confused what I am talking about.
Anybody here knows what is this bolt's toyota part number? Proper name? Do
you guys have access to the toyota parts ordering system and could help me
I would apreciate it greatly.
It is called the RH driveshaft centre bearing lockbolt, and is shown
although the plastic plug is not shown. You could make your own out of
nylon or teflon, the dimensions would not be critical, just a few mm
longer than the difference between bolt length and hole depth.
Yes, I saw the bolt on the original toyota shop manual diagrams, here
http://www.turboninjas.com/camry/sa.pdf page 21. The problem is that they do
not list the part number, so it is hard to order it. The guy at the parts
counter at the toyota dealership couln't match the diagram I have printed
and shown him (page 21) to his computer screens - on his screen this bearing
mount did not have the screw or bolt. I looked at the same screen with him
because we could not believe the diagrams looked differently. I have double
checked we are looking at 1995 camry LE 4 cylinder, everything matched other
than the bolt was not there on his diagram, so I could not get the part
number or order it.
Making the plug myself... hm... I could, but I would rather get the new bolt
and be sure it is right.
Is there a place online I can look for toyota part numbers and order them
Or the dealer is the only choice I have?
