no more clunky change in 3000m
Discussion
I now have a nice quite gear change and journey !
all year I have heard a nasty clonk when changing gear, very careful changes was the only remedy.
I gradually worked on problems that were obvious; the gearbox rear bearing was shot, so I replaced the gearbox housing, I also had the prop rebuilt, just in case it was out of balance causing problems with the bearing.
Adrian @ TVR Exactly advised that the diff cradle was probably broken, but careful examination (in situ) didn't show any cracks.
I did notice that the O/S front diff mount was perished so I picked up a set of Poly replacements, front and rear.
The gearbox work only mildly improved things, so I moved on and had the drive shaft UJ's replaced. While refitting the shafts i noticed that the N/S bearing had more play in it than it did earlier in the year, so I sent that off for adrian to do his usual magic.
I decided that while the shaft was out I needed to replace the diff mounts so I started to plan for diff work...
A friend in the Triumph world had a rebuilt diff that had been salvaged from a TR6 fire and it happened to be the same ratio, so with Adrian's advice I managed to remove my diff and cradle from the N/S wheel well.
(my internet research had indicated that I needed to lift the body or cut out an access hatch... as I have a TR6 diff I needed neither. I had already removed the N/S bearing/shaft, so I disconnected the hand brake cable from its inserts in the cradle, dropped the lower wishbone and then separated the cradle/diff in situ and they both come out in a matter of hours.)
In went the replacement with new poly bushes. Oil, rubber boots, bolts, nylocs etc drive shaft, brake pads, drum, and not forgetting to make sure the handbrake was reseated in the cradle slots !
no spare bolts left over, no spare nylocs or washers... all bolts torqued... wheels on and a test drive this evening...
all it took :
Rear gearbox housing,
Rebuilt prop,
Six UJs,
Reconditioned Differential,
Poly diff mounts
Rebuilt O/S bearing.
new oil in gearbox and diff
drive shaft gaiters
Patience and bruises
Advice and rebuild services from Adrian
cause of the clonk in the end ? at some point the cradle at the front of the diff had cracked, it had caused the prop/gearbox problem ( adrian was right), but when the cradle was welded the other problems were left...
very happy with the results;
now onto the source of drip causing wet ankles....
