What should I watch out for ? High mileage

07 5.7 234,500 miles. What should I look out for and replace at 236k I'm going to change the oil .(I change it every 3k ) coolant flush , change differential fluid , change power steering fluid , cabin air filter , engine air filter . What else should I watch for and maybe replace before it breaks ? Also I was in a wreck recently but all has been fixed since . A lady in a Ford focus ran the stop sign and I hit her going 40 mph. I included the part list incase any of you were wondering.

 

Welcome mate! I'm brand new here myself but I think I'd probably be

looking for a job closer to home!!

 

Thank you .What do you mean my job I just recently got is about 10 miles max . I bought the truck with 225k

 

My bad, Trevor! I just assumed you were 1st owner. Were it me, I'd hope for the best but be prepared for the worst. That's not all THAT Many miles for a Toy but keep an eye on bearings, suspension and steering components.

Good luck with your new old rig!

 

I would check to see if the transmission fluid has been changed yet, if it has I’d change it again ( do NOT flush it) but if it’s the original I’d be a little cautious. Also check the spark plugs, upper and lower ball joints and tie rods to see if they need any attention.

 

That's alright . Will do thank you

 

Looks like the majority of the damage was cosmetic. Can't see anything that jumps out. No need for coolant flush as they did that as part of the repair.
As for items to look out for -

Water Pump - they tend to leak in the '07/'08 model years.
Serpentine Belt - safe to assume that it's been replaced once. I would replace it.
Wheel bearings - some folks have had to replace. But others haven't.
Brakes - have then been checked/replaced recently? With the ATRAC system brake pads seem to wear out faster than most.
Fluid Update - you already mentioned that.
Struts/Shocks

That's literally about all there is to look for. These trucks will literally run forever with very little cost (unless the truck came from rust belt) then take it to Toyota and have a new one put in it.

 

Thank you I'll be sure to look out for those . Yes I replaced the rear pads and the rear rotors . I want to replace the front pads because my passenger side is wearing werid . I defiantly want to do the bearings when I have the money to just as preventative maintenance and also would want to replace the shocks as well .

 

A compression test would ease my mine at that mileage. Its a doable diy task and you probably could get a loaner tool from the parts store.

If you're gonna do the plugs any ways, why not?

Also, i would leave the wheel bearing alone for now. If they arent giving an audible sign of going bad then dont worry about them. When you start to hear them, you typically have a little time before you must change them.

 

Never thought about that thank you I'm thinking 250k changing the plugs I checked them a while ago. Just a parts store rental ?

 

A rental or maybe even for free with a deposit.
Im not positive but i feel like ive seen them on the loaner tool list at autozone.

 

Personally I would just run it as is and do the normal maintenance as needed. The 5.7 has a timing chain so you don't have to worry about changing it like a rubber belt. What's a compression test going to tell you? That your engine is worn out? Then what? You're not going to rebuild it. If it would give you peace of mind then sure but with that kind of mileage you are still going to be concerned about the transmission (as others have said changing the fluid is a good idea). Does your state require a yearly inspection? We do and most of the wear items (ball joints, bearings, etc.) are checked. Do you have any service records? With 250k miles on it I would be thinking of changing a few parts that if they die at the wrong time it would make life suck. The starter comes to mind. Nothing like driving on a trip and having it go 300 miles from home. I wouldn't work it too hard.

 

No they don't do safety anymore just emissions. No I dont have service records . I'm just nervous about changing the transmission fluid. Never thought the starter I'll add that to my list . Wouldn't work the starter or my truck too hard ? Thank you for your input

 

Transmission fluid is easy. Just drain plug and then refill. Don't flush. You won't get all of the fluid but it's not a big deal.

The starter is a huge PIA to change from all the DIY's that I've seen. Because your truck has that many miles my bet would be a ton of highway miles which means the starter wasn't engaged as often as a city truck. The ball-joints, etc are easier to check. Most of the time you get a ton of audible feedback from the suspension when the parts are worn-out and ready to be replaced. If your truck feels and sounds tight then odds are it is.

If I were you - I'd drain and fill the transmission. Replace diff fluids do an oil change update filters and then drive the hell out of it. Odds are the truck is ready to go another 200K miles. Don't overthink it.
