I have heard from somebody that the Niva's transfer box is inclined to not last as long as it should. IS this true?

Hi. Gearbox is a bit of a weak point on the niva.

The NIVA gearbox, transfer case and diffs are operating well within their design specifications. The problems in the past was mainly due to difficulty in obtaining spares and support. Spares can now freely be imported, workshop manuals are available for download and the Forum has very knowledgeable members who can give you on-line advice Poor maintenance by previous owners was in my opinion, the biggest contributor to the bad reputation that NIVA had or may still have among the public at large

Hi Spikes
You have hit the nail on the head, poor or no maintenance in my opinion is the biggest contributor to the poor reputation the Niva has.

Hi Citfield
There is no problem with the transfer case, it is completely reliable. The gearbox is more suspect but even here if it has the lock washer on the output flange and the oil is changed regularly it will last. Marius has had his Niva for I think 10 years and has opened the box once and since he fitted the lock washer the box has been trouble free. Remember the Niva is a very old design and in those days there was no such thing as extended service intervals. Service it every 10000kms or once a year and it will be a reliable form of transport.

The TC on the Niva is considered to be extremely solid and reliable - most probably because the design is very simple. The TC has also been widely used by many racing teams in the past because it is considered to be a very solid design.
Apart from the fact that the 5th speed on the gearbox is basically a "add-on" I would still consider it to be a fairly solid (simple) design. It's weakest link in my opinion is the tiny needle bearing between the two shafts - but that can even last a fairly long time.

Hi
I have heard of very few problems with the TC, I have been running mine as a RWD for a while now due to a front diff problem. I believe others have run as a RWD for an extended period of time due to front diff problems.
My front diff problems were ultimately caused by a broken left front engine mount which lead to fatigue and eventual failure of some bearings.
The worst problem I have with the GB is a leak from one of the seals which I am trying to replace at the moment, if only I could loosen the nut holding the top shaft in place. The TC has not given any problems at all. What you might find, which some people attribute to TC problems, is vibrations due to non alignment of the GB, CV, TC and prop shafts (in any combination of those).

Tjeers Steve Hi Steve I assume you were referring to the nut which holds the output Flange in place. If so - I have made myself a special tool, by welding two pieces of flat iron together at a 90 deg angle . It really makes it easy to loosen that specific Nut, and I think all owners who might have any in tension of repairing their own Gearboxes, should try to get hold of a tool like that. I will post pics of the tool as soon as possible - hopefully tomorrow evening. Danie

Hi
I have had my GB redone not to long ago. There is no issue with this and it runs very well. I do have a very high pitch sound in 4th from 90kmh up, and it dies down as soon as I accelerate up a hill or release the accelerator pedal. Not to sure if this is supposed to be there. Is there anybody that has the same sounds?

Michael Hi Michael I assume your Lada has got a 5 speed 'Box, and you only hear this noise while you are driving in 4th gear? Danie

Sounds like a 4th gear that is chipped or one tooth broken.

Hi
Danie yes it has 5 speed box. The noise is between 90 to just over 100 in 4th. The box was checked 1000 km ago and all broken and rusted bearings and parts replaced. There is no vibration or any issues, just the high pitch noise.

Hi Michael
Sorry to say - I think whoever has had a look at your gearbox, has done a "backyard job".
There should be no difference in noise levels - should the noise levels between 4th and 5th gear are compared.

My money is still on a chiped or broken tooth on 4th.

Hi
The Gearbox was was done at Jan from Centurion Lada. This was because the lada stood for some time and the bearings rusted becuase of that and the one shaft was shot. He has replaced all parts and tested. He is the only person that I know in JHB are that works on Lada's.
Any feedback on where to go or who to ask will be welcome.

Hi Michael
Maybe everything is not just doom and gloom - thinking back, I realize that my Lada's gearbox did have a slight wining noise as well. As far as I can remember, the noise did not change at different gears (i.e. 4th and 5th gear) though.
My first thought when I saw your initial comment, was that the noise at your gearbox is quite severe - but hopefully I am wrong and more owners will pass some comments.

4th gear on Rusti used to be as loud as a F18 at full throttle, Vincent and I had to use our opera voices to talk to each other. Maybe he has a pointer or three

That could be disintegrating and causing the noise as 4th is the only gear when the power is directly through the gb Regards Vincent

HI Micheal I ran my LADA as a 2 wheel drive for about 6 months which included a trip to Lesotho and Sani pass The TC whined the whole way in 4th just like you explained I discovered that because 4th gear is 1:1 the noise from the diff travels up the propshaft and it sounds like the TC is making the noise Long story short I stripped the diff and replaced all the bearings and VOILA no more whining noise from anywhere I am now also back to 4x4 I know it might sound crazy but it worked Hope this helps Regards Bill

Hi Bill
Many thanks for the info.
At least we now know that the whining noise ( in some cases at least) is coming from the Transfer Box, and not the Lada gearbox.

Hi Danie
The way I read Bill's observations, are that the whine actually came from the diff, and not the TC.
