+1 on info above. Yes all the info I'm referring is to the fill plug. The drain plug is a piece of cake. Again make sure to tackle the fill plug first before you drain the diff. I reused the OEM crush washers no leaks.

 

awesome thanks for all the info, i came across some other information on this forums where people were saying fill and train plugs were 10mm hex bolts

 

I have a 2010 AWD 250. The front diff has bolts. The rear has 2 hex head allen head plugs. I'm not sure if it changed through out the years. For the front if it has the bolt for the fill plug. You'll need some long extensions.

 

Hey Mike! I had little bit of time last night to look around under the car. So yeah steering rack knuckle where steering wheel connects to the rack is defiantly blocking the fill bolt. Now did you remove the two 8mm bolts from the knuckle where steering wheel connects to the rack or the actual two bolts that how the steering rack to the sub frame ?

 

The 2 from the subframe. Both are 19mm nut, and bolt. You'll have to prop it up to get it out of your way. It requires a 1/4 drive 14mm integrated socket swivel. With long extensions. As you can see there is not much room to work with. Like I said before make sure the socket is planted well on the bolt. The bolts tend to strip easy and get rounded.

 

ok thanks for the info, looks like ill be working on it this weekend. i'm going to gather all the tools necessary for the job then knock it out.

 

Everytime i read these threads i leave more confused and with a headache then when I started out. I then sit around debating on what where and who to do my services. I think everyone needs to not answer unless they actually know the answer. Or get some actual Lexus mechanics in here to answer peoples question. And just answer with Yes or No.

LMAO LOL!!!!!

 

Here you go. Read this thread: LOL it's already made the esiest way. If you're a DIY guy you'll be able to manage.

It's a tight spot I had to find a better one.

New member here. I messed with that front diff fill bolt on my 2014 IS250 today, and could not get a clear shot on it. I even tried swivel extension, a universal 14mm socket and no dice. I think I am going to have to detach the steering rack. Even then, I am not sure if its doable. There has to be a secret to this. I cannot imagine the Lexus tech has to go through heroic efforts to change someone's diff fluid.

 

Scroll to the bottom where it mentions the extra long aviation wrenches.

 

I used a standard ratchet wrench to remove the fill bolt from below. It's a tight fit, but you can use a hammer to tap on the wrench to break the bolt loose. Just make sure the wrench is on straight, otherwise the bolt will round out. Filled using a cheap hand pump bought at harbor freight. I then used a long magnetic telescopic tool wand (also purchased at hf) to position the fill bolt in place. Then had to maneuver my fingers around the power steering rack to get it started. Finally once the bolt was in place, used the ratchet wrench to tighten. It was probably 7/10 as far a difficulty goes. Hard, but doable with lots of patience involved.

 

is this correct?

 

Yes sir, that's the correct location
