Hi all I hope this the right place to post this question I have as above and was wondering if anyone could advise or recommend someone or some place that would inspect it for me I purchased it a while ago to convert my soarer its out of a soarer but rather that fitting it and then finding out theres problems I would prefer to get it looked at first cheers;)

I think it's a pretty standard gearbox, so any competent gearbox place should be able to do it. Might be worth checking on the Mk3 forum.

 

There are some rebuild articles on the web, although they all seem to be the 4WD version.

 

For example: http://www.4x4wire.com/toyota/tech/r151f/

 

There are also uprated parts available from Marlin Crawler (I think Driftmotion sell them).

Half a day 1 1/2 hrs on the ramp to pull it out I hope but the trouble is once I go manual there's no going back and the car will be out of comission till its sorted that's really why I was thinking of getting it checked first but chris is right its worth taking the risk only problem Im aware of on this box is 1st gear trust washer which I have got from martin in the states hence why I was thinking of going this route ;)

To fully strip and rebuild is not a five minute job, and, to be honest, if you did get it stripped you might as well put new bearings and synchro rings in it, for which price you could probably have been well on the way to a Getrag. I'd just fit it and hope.

 

Would you rate the getrag over the r154??
