rear main

Any experience with this procedure. Have engine out and will do clutch TOB, PP etc. How complex is the rear main seal replacement? Can it be done one piece from the outside.

Hey all - so I’m prepping to possibly have to replace my rear main if I can pinpoint that’s the source of my leak. In looking up the seal part numbers I get the following. 90311-99065 90311-99001 Where the 99001 is listed for 84-87 FJ60. I have an 888000 serial number motor so I think I’m in...

Getting ready to swap transmission/transfer between my 2013 and 2015 200s. Why? See my build thread. While I'm in there (my favorite words), I figure I might as well replace the rear main on the 2015. Do I need anything more than the seal itself (p/n 9031195013)? There is also a rear seal...

Hi all, first post and new (to me) GX owner. 07, non-nav with great maintenance records and all. Rides great and all that, but was cleaning up some really small residual oil when I was underneath the truck today. Right on the main seal, not enough to make a drip, but noticed it wet when I wiped...

Hi all, I'm doing a rear main seal on my 1hz, but seal housing looks incorrect, (see pics, can see gap at top) motor is second hand and has leaked from word go. Was wondering if 1hdt and 1hz have differences in crank or bearings causing 1hz crank to sit lower. If so i will order correct housing...

Was under my 06 LX470 the other day and noticed that there some oil that appeared to be seeping out right were the engine and bell housing meet on the bottom. Nothing dripping and I have not ever noticed a puddle of oil on the ground where I park, but I checked the oil level and sure enough it...

I think I have a rear main seal that is leaking pretty good any one had this issue before? I looks to be leaking there the block meets the transmission. Just looking for what i can expect from anyone who has messed with this before.

Ok so after completely destroying my rear main seal trying to get it in are there any tricks to this!? I used a pipe the same diameter as the seal and it just wasn't going in!! The outer diameter of the seal just seems about 2 mil too big. Here are some pics. Any help would be greatly...

so I'm changing all my fluids and noticed my engine oil is wheeping at the engine/trans seal. It looks like I may have caught it on a stick as it's bent. I didn't cheap my oil level prior to draining. I haven't noticed any spots or pressure changes. Anyways should the gasket be bent like...

Gents, I'm working on a 1970 with the original F engine. My gear is back from the machine shop. I have the engine torn down and I'm working to install the crank, photos below. After reading several threads it seems a minor amount of RTV is used on the rear cap to prevent oil leakage (threads...
