Walker570 Posted May 15, 2019 Report Share Posted May 15, 2019 I have just replaced the front driveshaft on my Landie 90 1989 model. The yokes on the old one was just starting to show signs of wear and they are not the earth to buy so decided to stick a new one on. The old one appeared to be short by about 1 1/2 inches and although the new one was listed as fitting this model it also appeared to be short by the same amount. Now the old one has been there since I have owned it and before, over 10yrs and has run no problem. The splines are just showing lear of the rubber cover. Any of you Landy experts with any views as to why and should I fit a different prop shaft ? The new one is running fine as did the old one. The vehicle has 127 miles to go for 200,000 miles, 130,000 in my possession. It has been converted to a V8 from a deisel but the gearbox/transfer box is still in the same position. Both shafts are 22 1/2 inches centre to centre of the universal joint. Quote Link to comment Share on other sites More sharing options...

ditchman Posted May 15, 2019 Report Share Posted May 15, 2019 well to be quite honest..............if you google drive shafts half shafts....they are the same thing......... 1 1/2" slack seems a bit excessive tho'............may be the axel is non-spec as it has been modified with a V8...

panoma1 Posted May 15, 2019 Report Share Posted May 15, 2019 Guys I knew used to change the diffs when fitting a V8 engine in a Series 2/3LR......dunno if that would explain the driveshaft length issue? Quote Link to comment Share on other sites More sharing options...

Walker570 Posted May 16, 2019 Author Report Share Posted May 16, 2019 Interesting. It is the front driveshaft from transfer box to diff. I have put a Range Rover back axle on which has disc brakes and is a direct replacement and makes no difference to the rear drive shaft. I cannot see any difference with the front diff to any other 90. The suspension has not been lifted, that's standard height. As said the original driveshaft has been on for ten years to my knowledge and may have been on since 1989 .... it looks that old anyway. Originally when I purchased it, it was fitted with the LT77 box and the low ratio transfer box. I put a high ratio transfer box on it, which outwardly is the same configuration. Front axle/diff looks standard. 12 hours ago, panoma1 said: Guys I knew used to change the diffs when fitting a V8 engine in a Series 2/3LR......dunno if that would explain the driveshaft length issue? That was.... I think..... just the innards to get a higher ratio. Quote Link to comment Share on other sites More sharing options...

If it's the propshaft my theory re: the driveshafts is out of the window! It's been many years since I have been under a Landpig..........but is there not a joint in the front propshaft which allows the splines to slide in and out when driving over rough terrain?

Always been a drive shaft in my world, but hope y'all now knwo what I am talking about. The very slight slackness in the yoke became apparent when my mechanic was fitting a new uni on the rear shaft. As always whilst it was up in the air he ran through all of his checks and found just a slight give, so I decided £70 was not going to break the bank and we would have a new one. Have a friend who is a retired developement engineer at the ORIGINAL Land Rover, Solihull, when they built PROPER off road working machines, I will give him a call as I know he keeps in touch with all the other team members. Thanks for your input, appreciated. Edited May 16, 2019 by Walker570 Quote Link to comment Share on other sites More sharing options...
jason g Posted June 3, 2019 Report Share Posted June 3, 2019 Could it be a discovery one there are slight differences I put a 90 one onto my 300tdi disco the UJ have more of an angle and it was cheap and late at night Quote Link to comment Share on other sites More sharing options...
Walker570 Posted June 4, 2019 Author Report Share Posted June 4, 2019 Still trying to find out. The parts listing is for 90s up to '91 and mine is '89 and not lifted or anything. The gearbox is on the original fittings and is a straight forward LT85 and transfer box. The truth will eventually out, but at the moment it is driving OK.

jeffgg Posted June 9, 2019 Report Share Posted June 9, 2019 You say it has a LT77 box and now you say it has a LT85 box Quote Link to comment Share on other sites More sharing options...

It was a straight forward change over and all fittings lined up the same. Still no further with getting answers. Quote Link to comment Share on other sites More sharing options...
