Towing a RWD S10 Blazer Sign In

I have a 1993 Chevy Blazer S10 RWD and am needing to tow it across country using a tow dolly with the front wheels off the ground. It seems I could just put it in neutral but I've heard I may have to disconnect the driveshaft. If so, how hard is this to do and...well, how would one go about doing that?

Yes you will need to disconnect the drive shaft or risk damage to the trans. It is not to difficult to remove the drive shaft itself, but if you tow the truck with it out you will likely leak trans fluid all over the place. There is a drive shaft disconnect that can be installed but it usually requires cutting the drive shaft and welding in new parts. It usually cost around $500 or so. If you do want to pull the drive shaft off then I would recommend dropping the pan on the tran and draining the fluid before towing. Good Luck

Re: Towing a RWD S10 Blazer Sign In

Thanks for the advice. I've been told by other people much the same things: I can either remove the entire drive shaft and install a plug of some sort or simply disconnect the driveshaft from the rear, where it connects to the U Joint, tie it up and duct tape the "caps" on the U joint. Though I'm not sure what caps are--I'm obviously no mechanic--I've heard it's only four bolts to disconnect the drive shaft, and surely I can figure out what to duct tape from there. I have to get under the car and check it all out, but surely there's a place to tie up the drive shaft. Although this seems fairly easy, any advice or comments on this course of action would be helpful. The move is budgeted down to the penny and I just don't have money to purchase a plug or the knowhow to remove the drive shaft. It seems the easiest course of action is the best in this case, and removing four bolts, tying it up and duct taping the caps seems easiest. But--is it the best?

Thanks again.

Hi,

Shaft really should be removed from rear differential. Ok: If I guess exactly what is at that connection I'd be wrong so I'll suggest either way it could be. Some use "U" bolt - four nuts, some are a plate with four bolts. If "U" bolt the bearing caps can just come off when not restrained by being in place so you would duct tape them in place trying not to let them fall off and all the little needles go flying. If so you could just get a new U-joint if all is lost - cheap as things go.

I'm pretty sure this driveshaft is just two U-joints and pulls right out of trans which will leak where shaft goes in. If you were just taking the shaft out for working on it or any reason it would only leak so much and quit with limited loss of ATF. This is going to be hauled with front up so rear would be down and with bumps etc on the way could leak a lot! As Jeff suggested, drain the ATF. You do that by dropping the pan by the bolts (I don't think it uses a drain plug) Put pan back on - good time to replace gasket and filter but don't refill till at destination. Essentially you are doing a trans oil and filter change in this process but not refilling for the trip and will have to finish then. The total # of quarts of ATF needed is not known by me but a guess would be about 5 quarts. Try to count what comes out so you know it will take that much later and top off with care not to overfill later.

Driveshaft: If there was a way to just leave it in place but disconnected for this trip you could avoid all this. Not that simple as it could fall out and we don't want to read about that. Best to remove shaft and store it in vehicle somehow. Cover the open trans end with plastic of some creation to prevent dirt and water from getting in there while enroute. It's oil so use plastic that will tolerate that and tie it on with your imagination. Tapes may not hold - wire or plastic wire ties perhaps -you decide.

Note on driveshaft: Index the position before you take anything apart. Use tire marker or paint - whatever works for you so you can put shaft back on in same position it was in when removed. This is for the rear position. Front won't matter. Save the hardware for later. Shaft will go on rear end one of two ways and will work either way. Best to keep original position if possible for balance. That position may have been lost over the years anyhow but best now to at least have it where it worked right before.
______________
If this is just RWD not 4X4 then towing with drive wheels off ground would save all this. That or a trailer keeping whole vehicle off the ground.

The issue is the driveshaft to trans will turn if wheels are turning and with engine off there's no lube for the transmission which is being turned by that driveshaft alone. That's ok for emergency limited towing but not for a trip and may be outlined in the owner's manual for the exact vehicle's drivetrain.

Pay attention to this as it is as important as you think!

Re: Towing a RWD S10 Blazer Sign In

Well...I'm speechless! Such a well thought out and in depth reply! I sincerely appreciate all the help I've received. Maybe now I should ask for donations so I can spring for the more expensive tow-dolly with all wheels off the ground! Lol...no, of course not. Actually I think the transmission could use a filter and fluid change, so maybe this is the time to get it done. One further question, though: Why would it be difficult to just tie up the drive shaft? Some people have said this would be a cinch while others, like yourself, have implied it would be difficult and not reliable.

Re: Towing a RWD S10 Blazer Sign In

Hope your eyes don't hurt - my middle name is VERBOS!

Yes - you could tie the shaft up - that's what I'd do but I have bars, brackets and clamps such that it wouldn't fall and if I didn't like my handiwork I'd take it off. Again - it's really only held from the back bolts to diff and the front just slides out but if it was secured VERY well it wouldn't. Keep in mind engine/trans will still move some relative to body/frame with bumps while towed too!

Tricky - I suggest taking it out for you. Can't risk that falling off as it could damage your own vehicle and then be a total street weapon. You have to plan to sustain pot holes and whatever road hazards enroute. Write this off as a trans fluid and filter service so you really take care of two things at once here. Also gives you a good feel for how good the U-joints are and you might find one or both ready to do also.

Be safe. Again - it is important. It is archived at this site somewhere with someone who had a problem after a long tow of perhaps about this same vehicle, did nothing with the driveshaft and it had ruined the trans!

Be safe,

T

Re: Towing a RWD S10 Blazer Sign In

Okay, good advice all the way around. I'll take it all into consideration and make a decision. Likely I'll take the whole thing out. Seems the best way to go. Before I started this whole train of thought I knew nothing about drive shafts or U Joints. After watching Youtube videos and talking to you guys I feel like an expert! Which is good. I think I can do it. :-)

Re: Towing a RWD S10 Blazer Sign In

I have one more question: It appears we'll have to tow the car initially between forty and fifty miles before we can disconnect the driveshaft. Will it hurt it to tow it this short distance in neutral?

Re: Towing a RWD S10 Blazer Sign In

Right out of an owner's manual for towing for a Ford (same ideas) suggests that it can in an emergency be towed in neutral at speeds up to 35mph for 50 miles. I still don't like that much.

If you do this A or B. With all care taken you could leave engine running or stop and run engine for a couple miles now and then along the trip. HEY - RUNNING AN ENGINE WITH THE VEHICLE UNATTENDED INSIDE IS DANGEROUS BY NATURE. That's not to say I suggest someone be in it either!

Guess: If you just stopped and ran the engine and engaged trans, R, N, D etc along route a couple times that would really help then back to N for more towing. The 35mph thing counts. I know that's annoying but pay attention. It's a pill but I'd probably stop every 15 miles and plain drive it.

The deal is that transmissions only have pumps in the front and are engine driven. If you are as old as dirt like I am you may recall ones with pumps on both ends! That pumping is what allow for hydraulically actuating everything in the trans, keeping it cooler and lubed. Just note that the old trick of pushing a car and putting it in gear with a failed starter to turn the engine won't work in an automatic as proof there's no hydraulic pressure to engage it. Manual trans would still "turn" the engine that way.

See if your own owner's manual has any special suggestions as well. This is discussed in all I've ever read,

Re: Towing a RWD S10 Blazer Sign In

Thanks for your help. I'll take it all into consideration. My owner's manual is sadly lacking in towing advice. It only tells you the best route to towing a manual or 4wd Blazer, but mine is automatic and RWD. Likely I'll end up driving 35MPH and stopping every fifteen miles or so to turn it on and shift gears. Other people have told me much the same thing.

Re: Towing a RWD S10 Blazer Sign In

Thanks to everybody for all the advice and we did make it safely on our nearly 800 mile trip. The moment before I was to disconnect the driveshaft our neighbor, who--had I only known!--is a mechanic came over and said "why are you doing that? It's rear wheel drive, the steering wheel locks--just back it up and tow it backwards!" And so I did, and so it worked splendidly. Now we know that you can tow a 1993 Chevy Blazer S10 RWD backwards, so long as the steering wheel locks.

Glad the trip went well. I asked if this was just rear wheel drive if you could haul it with "drive" wheels off ground which is all any vehicle needs. Sorry that got lost is the length of the thread. I didn't know what kind of tow thing you were using but when towing rear only drive vehicles you then need to secure the steering wheel from turning which they do anyway if locking mechanism works properly but most would still suggest tieing it so it can't turn much if something were to happen.

Again - Glad to hear trip went well with no hassles,

Re: Towing a RWD S10 Blazer Sign In

No no, that was absolutely my fault. Now that you bring it to my attention I do recall reading that. Somehow or another it slipped my mind. Well, it all worked out, and thanks again for all the help. I do appreciate it.
